Annotation:
Dans l'espoir de mettre en évidence une activité anticytokinine dans les dérivés des n-phenyl-n-pyridylurees, 10 molécules, 9 urées et un carbamate, analogues structuraux de la n-benzyl-n-(2,6-dichloropyrid-4-yl) urée ont été synthétisés. Ces composés ont été obtenus par réaction de pyridylisocyanates ou de pyridylcarbamates avec des dérivés amines ou l'alcool benzylique. Nous avons par ailleurs mis en évidence l'impossibilité d'obtenir des urées par réaction des 4-amino-pyridines 2-substituées et de l'isocyanate de benzyle à cause de réactions secondaires. Les tests biologiques ont montré que certaines des molécules préparées possédaient un fort pouvoir inhibiteur de la croissance cellulaire. L'activité anticytokinine n'a pas été détectée. L'étude de la photolyse de la n-(6-azido-2-chloropyrid-4-yl)-n-phenyluree, réactif de marquage par photoaffinité des protéines affines des cytokinines, en présence de nucléophiles, a mis en évidence l'agrandissement du cycle pyridine en diazépine ainsi que la substitution de l'atome de chlore. La position de l'équilibre azidotetrazole dans cette azidopyridine a été étudiée dans différents solvants. Elle peut influer sur la nature des produits de photolyse, mais l'existence de cet équilibre n'est pas préjudiciable pour le marquage par photoaffinité.

Annotation:
Stilbene containing polymers are a group of interesting and versatile polymers. The pendent phenyl ring along the polymer backbone can impart unusual rigidity to the polymer backbone due to steric repulsion. By functionalizing stilbene, a variety of functional groups and ionic groups can be precisely placed along the polymer chain with tunable charge density. Therefore, stilbene containing polymers are potentially rod-like polyelectrolytes with controllable charges and charge density. They are the basis of a novel group of rigid synthetic polyelectrolytes and can be used for furthering our knowledge of rigid polyelectrolytes.

A novel series of methyl substituted stilbenes were synthesized and copolymerized with maleic anhydride. A conversion-time study was undertaken to understand the methyl substituent effect on copolymerization rates. Methyl substituted stilbene-maleic anhydride copolymer compositions were determined by quantitative 13C 1D NMR. SEC measurements showed the weight average molecular weights of these copolymers vary from 3 000 to over 1 000 000 g/mol. No glass transition temperature or crystalline melting temperature was observed between 0 oC and 250 oC by DSC. TGA showed that these polymers have 5% weight loss around 290 oC.

Precursors to a polycation and a polyanion based on functionalized stilbenes and maleimides have been prepared: poly(di-t-butyl-(E)-4,4â -stilbenedicarboxylate-co- N-(4-(t-butoxycarbonyl)phenyl)maleimide) and poly(N,N,Nâ ,Nâ -tetraalkyl-4,4â -di- aminostilbenes-co-N-4-(Nâ ,Nâ -dimethylaminophenyl)-maleimide). These copolymer precursors were characterized by 1H NMR, SEC, TGA, and DSC. The 1H NMR spectrum indicated the rigidity of copolymer backbones. SEC measurements showed the weight average molecular weights of these copolymers vary from 5 000 to 11 700 g/mol. No glass transition temperature or crystalline melting temperature was observed between 0 oC and 175 oC by DSC for poly(di-t-butyl-(E)-4,4â -stilbenedicarboxylate-co-N-(4-(t-butoxy- carbonyl)phenyl)maleimide). TGA showed that this polymer has 5% weight loss around 210 oC and 26% weight loss on the first stage of decomposition which corresponds to elimination of t-butyl functional group in the copolymer.

The homopolymerization of EMS-III via free radical polymerization, anionic polymerization and cationic polymerization was attempted. However, no polymer was obtained from any of these polymerization methods. In anionic polymerization, the solution changed to red upon the addition of the initiator sec-bu-Li, indicating the successful addition of the sec-bu-Li to EMS-III. However, the initiated monomer did not propagate to form homopolymer.

Annotation:
La reactivite des n-phenyl-trimethylsilylcetenimines (heterocumulenes faciles d'acces a partir d'un imidothioester silyle) vis-a-vis de reactifs nucleophiles et electrophiles a ete examinee. Le groupe trimethylsilyle sur le carbone stabilise ces cetenimines en reduisant sensiblement leur reactivite en tant qu'electrophiles et apporte donc une contribution ambivalente a la reactivite. Les additions de nucleophiles (organometalliques, alcools, eau, thiols, amines et hydrogenophosphonates) ont lieu sur le carbone central , a temperature ambiante et s'accompagnent souvent d'une desilylation partielle. Cependant, dans certains cas (phenol, thiols), des procedures ont ete mises au point pour eviter toute desilylation. De plus, il a ete montre qu'il etait possible d'utiliser ces heterocumulenes silyles pour realiser a partir de composes difonctionnels des syntheses one-pot d'heterocycles. En particulier, la synthese de n-phenyl-iminocoumarines et de n-phenyl-pyrrolizine. L'addition de reactifs electrophiles sur les cetenimines silylees a ete examinee. Le chlorure de benzenesulfanyle s'additionne rapidement a basse temperature pour conduire a des chlorures d'imidoyles plus ou moins stables et souvent precurseurs de nouvelles cetenimines sulfurees. D'autres reactifs electrophiles (p-tols(o)#2cl, me#3sicl, me#3sibr, accl, (ro)#2p(o)cl), insuffisamment reactifs vis-a-vis des cetenimines silylees ne reagissent que sur le derive lithie de la n-phenyl-trimethylsilylcetenimine (en equilibre avec la forme ynamine lithiee). La regioselectivite (c- ou n-addition) depend du reactif utilise. Ces additions electrophiles ont permis d'obtenir dans la plupart des cas de nouveaux synthons (cetenimines, derives d'ynamines, chlorure d'imidoyles) fonctionnalises dont la reactivite et les potentialites synthetiques seront interessantes a examiner.

Annotation:
Endoproteinase Glu-C (EPGIu-C, EC 3.4.21.19), an enzyme isolated from the bacteria Staphylococcus aureus, has been found to cleave specifically at the carboxyl-terminal side of glutamyl and aspartyl peptide bonds. EPGIu-C has been reported to be stable and active in the presence of common denaturants such as guanidinium chloride, urea and sodium dodecyl sulfate (Drapeau, G.R. (1977) Methods in Enzymology, 47:189-191). In order assess the denaturant stability and activity of EPGIu-C, the effect of three common protein denaturants, guanidinium chloride, urea, and sodium dodecyl sulfate (SDS) on the proteolytic activity of EPGIu-C was studied.The kinetics of the hydrolyis reaction catalyzed by EPGIu-C was determined using the chromophoric substrate N-tBOC-L-glutamic acid-a-phenyl ester (BGPE).To compare theurea is significantly greater at the higher concentrations of urea. These results suggest that a complete cleavage of proteins substrate by EPGlu-C might occur more rapidly in 8.0 M urea than in 6.0 M GuCl, since EPGlu-C will be operating at a significantly higher catalytic efficiency in the urea solution.

Neste trabalho foi proposto um sistema de análises por injeção sequencial (SIA) para determinação espectrofotométrica da capacidade antioxidante em amostras de bebidas, a partir da geração “in situ” do radical derivado do reagente N-fenil-1,4-fenilenodiamino (NFFD•+). O radical NFFD•+ foi produzido em linha pela oxidação do NFFD empregando o Fe3+ como oxidante. Na otimização do sistema SIA foram avaliados os seguintes parâmetros: ordem de aspiração dos reagentes e amostra, estabilidade da solução de NFFD, pH da amostra, proporção NFFD/Fe3+, volumes das soluções dos reagentes e amostra e tempo de interrupção do fluxo. O ácido gálico foi empregado como padrão de calibração para os ensaios. Após as etapas de otimização univariada do método proposto obteve-se faixa linear de 10 a 40 mg L-1, com limites de detecção (3σ) de 1,0 mg L-1 e quantificação (10σ) de 3,3 mg L-1, respectivamente. Para avaliar o método proposto, foram realizados testes de reatividade do radical NFFD•+ frente a compostos fenólicos, tiólicos e de outra natureza. A redução do sinal analítico frente a inibição do radical derivado do NFFD foi mais pronunciada para ácido ascórbico, ácido tânico e cisteína, nesta ordem. A capacidade antioxidante com o radical derivado do NFFD foi avaliada em amostras de vinhos e chás, e os resultados foram concordantes com os métodos de referência (Folin-Denis, ABTS e DPPH), de acordo com o coeficiente de correlação, além do ensaio com radical DMPD•+, baseado no teste t. Assim a amina NFFD por ser utilizada para avaliação da atividade antioxidante em amostras de bebidas. Adicionalmente, as amostras de vinhos foram submetidas a testes de estabilidade temporal e avaliação do efeito do processo de ozonização em relação à variação da capacidade antioxidante
In this work was proposed a sequential injection system for spectrophotometric determination of antioxidant capacity in beverage samples with “in situ” radical generation from N-phenyl-1,4-phenylenediamine (NFFD•+). The radical NFFD•+ was produced by on line oxidation of NFFD employing Fe3+ as oxidant. The optimization of SIA system evaluated: aspiration order of reagents and sample, stability of the NFFD solution, sample pH, NFFD/Fe3+ proportion, reagents and sample volumes and stopped flow time. The gallic acid was used as standard of antioxidant compound for proposed sequential injection method. After chemical and physical univarieted optimization the linear range obtained in gallic acid concentration was from 10 to 40 mg L-1, with detection (3σ) and quantification (10σ) limits of 1.0 and 3.3 mg L-1, respectively. To evaluate selective of radical, studies of reactivity were performed with NFFD•+ and phenolic and thiol molecules and others compounds. The reducing capacity of NFFD•+ radical was observed preferentially for ascorbic acid, tannic acid and cysteine in this order. The antioxidant capacity with NFFD•+ radical was measured in samples of wines, infusions and teas. The results were agreement with the references methods (Folin-Denis, ABTS and DPPH), in accord with correlation coefficient, and additionally with the radical DMPD•+, based on t test. This way, the SIA spectrophotometric method exploring the radical NFFD•+ can be employed for the antioxidant capacity measured. Additionally, temporal stability and the ozonization effect in wine samples were evaluated using antioxidant capacity as parameter .

Les etudes biologiques ont montre qu'un derive du practolol dans lequel le groupe acetamido en para a ete remplace par hncoch#2ch#2ch=chi (ami-9), possede les caracteristiques necessaires a un marqueur des recepteurs -adrenergiques. La synthese de l'enantiomere s (la seule forme active) et marque avec une haute activite specifique a constitue le premier objectif de ce travail. Pour verifier la purete enantiomere avec laquelle ami-9s a ete obtenu, nous avons mis au point une methode de determination de cette purete a l'aide d'un agent de derivation chiral, l'acide 2-fluoro-2-phenylacetique. Cette methode peut etre generalisee aux -bloquants du groupe b et etendue a la determination de la configuration des -aminoalcools. Le second objectif consistait a preparer de nouveaux analogues iodes du practolol en changeant les substituants soit sur l'azote de la fonction amine soit sur celui de la partie amide : - le groupe isopropyle par ch#2ch=chi et (ch#3)#2cch=chi, - le groupe nhcoch#3 par ich=chch#2ncoch#3 et hncooch#2ch=chi.

To take advantage of self-assembly to construct a variety of supramolecular architectures and polymeric networks with potential applications is a challenging in crystal engineering. In this thesis, we designed and synthesized two unsymmetrical pyridyl-amine ligands as bridging-bidentates,N-(4-(4-aminophenoxy)phenyl)isonicotinamide (papoa) and N-(4-(4-aminophenylthio)phenyl)isonicotinamide (papsa), to react with ZnX2 (X = Cl, Br, I, NO3)、CdX2 (X = NO3, ClO4), and CuI to give a series of coordination polymers. We try to investigate the anion and solvent effects on the formation of metal-organic frameworks. The complexes studied in this thesis contain [Zn(papoa)Br2]2 (2), [Zn(papoa)I2]2(3),[Zn(papoi)Cl2]2(1''),[Zn(papoi)Br2]2(2''), [Zn(papoa)(NO3)2]2 (4a), [Zn(papoa)(NO3)2]n (4b), [Zn(papsa)Cl2]2 (5), [Zn(papsa)Br2]2 (6), [Cd(papoa)(NO3)2]n (8), {[Cd(papoa)(MeCN)2]- (ClO4)2}n (9a), [Cd(papoa)(ClO4)2]n (9b) and [Cu2(papoa)2I2]n (10), which are isolated and structurally characterized by the X-ray diffraction study. The X-ray analysis reveals the formation of 0-D macrocyclic structures for 2, 3, 4a, 5, and 6, 1-D double zigzag chains for 4b, 8, and 9a, and a 2-D wave framework for 9b. The 0-D and 1-D complexes can be extended into multidimensional structures by hydrogen bonds. Each macrocycle includes two ZnX2 units, with roughly tetrahedral coordination geometries at Cd(II) centers, and two papoa (or papsa). When Zn(II) nitrate is reacted with papoa in the presence of different solvents, two coordinated patterns for 4a and 4b can be obtained. 4a involves two papoa and two nitrate units, whereas 4b is composed of four papoa and two nitrate. These Zn(II) complexes display blue emission in the solid state, and can be probably assigned to an intraligand transition (IL). When Cd(II) perchlorate is reacted with papoa in the presence of different solvents, two coordinated patterns for 9a and 9b can be also obtained. Both structures of 9a and 9b have roughly octahedral geometries at Cd(II) centers and four ligands(papoa), whereas the axial coordination for 9a is acetonitrile and 9b is perchlorate. Cd(II) complexes also display emissions in the solid state, and they can be probably assigned to a metal-to-ligand charge-transfer (MLCT) transition. Moreover, the reaction of papoa with CuI can form 1D coordination polymer, 10, where the interesting Cu2I2 unit with a short CuI???CuI contact (2.666 Å) was expected to be responsible for the intriguing emission properties. Finally, when zinc halides were reacted with papoa in acetone, ZnX2 (X = Cl,Br) can act as a transition-metal-based catalyst to catalyze a nucleophilic attack on the carbonyl group by the amine led to the formation of Zn(II)-imine complexess, 1’ and 2’, following dehydration.

N-phenyl-N'-sulfinylhydrazine (PhNHNSO) is known to form hydrogen bonded dimers in the solid. Recent experimental studies have shown that the dimerization of PhNHNSO is very sensitive towards the position of a substituent on the aromatic ring. It was found that upon introduction of a substituent in ortho position, dimerization did not occur. However, substitution in meta and para position did not hinder dimer formation. This study was carried out to understand why certain PhNHNSOs dimerize, while others do not. The effects of substituent and solvent on dimerization were investigated by means of different computational methods. In general, density-functional theory calculations were combined with topological analyses of the electron density. The relative energies revealed a preference of the syn configuration over other configurations of the unsubstituted monomer. The introduction of substituents in ortho position led to less stable monomers as well as dimers, whereas meta and para substitution had only a small effect on monomer and dimer stabilities. The geometries, frequencies and electron densities of N-H and S=O bonds are more affected by ortho than by meta and para substitution, and the ortho dimers showed weaker intermolecular interactions because of twisted geometries. The observed intermolecular N-H---O and C-H---O interactions in the dimers are characterized as hydrogen and anti-hydrogen bonds, respectively. Increasing solvent polarity weakens the dimers. The topological properties, structural parameters and energies showed an unfavourable dimerization for ortho substituted PhNHNSO monomers, which is consistent with the experimental results

This thesis discusses the chemistry of Copper(II) and Silver(I) complexes containing N-Phenyl-N’-cyano-formamidine. The reactions of unsymmetrical N-Phenyl-N’-cyano-formamidine (HPhCNF) with Cu(NO3)2 • 3H2O, CuCl2 • 2H2O and AgX (X = NO3-, SO3CF3-, BF4- and ClO4-) afforded the complexes Cu(NO3)2(HPhCNF)2•THF, 1, Cu4OCl6(HPhCNF)2(H2O)2•4THF 2, [Ag(HPhCNF)3](NO3), 3, {Ag(HPhCNF)(SO3CF3)}∞, 4, {[Ag(HPhCNF)](X)}∞ (X = BF4, 5; ClO4, 6) and {Ag(HPhCNF)(ClO4)}∞, 7, which were characterized by single-crystal X-ray diffraction method and elemental analyses. The copper atom in complex 1 is bonded to two trans nitrogen atoms of cyano group of HPhCNF, two trans oxygen atoms of nitrate and one THF group forming the five coordinated distorted square pyramidal. In the crystal structures of 1, C-H•••O and N-H•••O hydrogen bonds are found to link the molecules. The complex 2 has a central Cu4OCl6 cluster encapsulating an oxo anion which are also coordinated by two N-Phenyl-N’-cyano-formamidine ligands and two H2O molecules. The Ag(I) metal centers in complex 3 shows a distorted triangular planer coordination geometry, which are coordinated by three nitrogen atoms of the cyano groups. The metal centers of complexes 4 ~ 6 are coordinated by two different nitrogen atoms of the bridging ligands, forming unique 1-D zig-zag chains. Each silver metal center of complex 7 is approximately tetrahedrally coordinated by two nitrogen atom, one oxygen donor atoms and three carbon atoms of the η3-phenyl group, forming the novel 2-D polymer sheets.

Numerous alkylating agents are one of the major classes of frontline chemotherapeutic drugs, such as oxaliplatin against colorectal cancer, cisplatin against lung and bladder cancers and mechlorethamine against multiple myeloma. Nitrogen mustard, the earliest member of alkylating agent family, still plays a key role in treatment of patients with Hodgkin’s disease and multiple myeloma. Alkylating agents may be used alone or in combination with other chemotherapeutic agents, such as MOPP (mechlorethamine combine with oncovin, procarbazine, and prednisone) for Hodgkin’s disease. Since alkylating agents in general non-selectively react and irreversibly bind to DNA as well as protein’s thiols, many unpleasant side effects, such as neutropenia and myelosuppression limit the use of alkylating agents in clinic. To resolve these problems, new series of water-soluble N-mustards link with various hydrophilic N-phenyl ω-dialkylaminolalkylamide or ω-cyclic aminoalkylamide moieties via urea linker were designed and synthesized by Dr. Tsann-Long Su (IBMS of Academia Sinica). DNA-affinic molecule can help compound to be more water soluble and bring compound to target site, and urea linker can reduce the chemical reactivity of N-mustard moiety. Using alamarBlue® cell viability assay, it was found that human colorectal cancer cell lines were relatively more sensitive to these water-soluble N-mustards as compared to other cancer cell lines. Among them, anticancer activity of BO-2094 was evaluated in nude mice bearing HCT-116 or H3347 xenografts. The results showed that BO-2094 given 30 mg/kg for 5 days significantly suppressed the tumor growth of HCT116 xenograft animal model. Furthermore, there is synergistic antitumor activity of BO-2094 in combination with 5-FU in human colon cancer HCT-116 cells. Significant anticancer activity of BO-2094 combined with 5-FU in nude mice bearing HCT-116 xenografts were also observed. Using TUNEL assay improved that BO-2094 could lead to cell apoptosis of human colorectal cancer tissue. Through alkaline agarose gel shift assay and modified comet assay, it was confirmed the potent activity of water-soluble N-mustards on induction of DNA interstrand cross-links. Meanwhile, G2/M arrest in HCT-116 cells treated with these newly synthesized water-soluble N-mustards was observed, whereas HCT-116 cell was arrested at the G2/M and S phase by treatment in combination with BO-2094 and 5-FU. These results implicate that BO-2094 warrants further development and preclinical studies.

This thesis is presented to investigate structural characterization and chemical properties of metal complexes which are composed of the N-phenyl-tripyridyltriamine ligand (H3ph-trptra) and transition metal ions. Mononuclear, octahedral transition metal complexes, [ML2]n+, containing the neutral tridentate H3ph-trptra ligand and a MnⅡ, FeⅡ, CoⅡ, NiⅡ, ZnⅡ, RuⅡor RhⅢ ion have been synthesized. All of the [M(H3ph-trptra)2]2+ ( M = CoⅡ, NiⅡ, ZnⅡ, RuⅡ) complexes reveal a distorted octahedral conformation with two tridentate meridionally coordinated H3ph-trptra ligands wrapped around the metal center in an all-anti conformation. The complexes [M(H3ph-trptra)X]n+ ( M = CuⅡ, X = CH3CN;M = PdⅡ, X = Cl ) reveal a distorted square planar conformation with a tridentate H3ph-trptra ligand coordinated to the metal ion in an all-anti conformation. According to the results of magnetic measurement, the electronic configurations of the central metal ions of mononuclear transition metal complexes ( MnⅡ, FeⅡ, CoⅡ, NiⅡ, CuⅡ) are paramagnetic. In related word, we are trying to synthesize multinuclear metal string complexes, and the complex [Ni5(m5-Hph-trptra)4Cl2] has been successfully synthesized and primitively characterized by FAB-mass spectrum.

In this thesis two series of new mesogenic compounds were prepared and their mesomorphic properties studied. All organic comounds were characterized by 1H and 13C-NMR spectroscopy. The metal complexes were characterized by IR spectroscopy and elemental analysis. The mesomorphic behavior was investigated using polarized optical microscopy (POM), differential scanning calorimetry (DSC), and temperature dependent powder X-ray diffraction measurements (XRD).   In series I, four Schiff bases derived from 1-(3,4-bis(alkoxy) phenyl)-3-hydroxyprop-2-en-1-ones (n = 10, 12, 14, 16) and their copper(II), nickel(II) and palladium(II) complexes were prepared. All the Schiff base ligands (n = 10, 12, 14, 16) exhibited hexagonal columnar phases (Colh). Palladium complexes (n = 10, 12, 14, 16) and Nickel complexes (n = 12, 16) complexes also columnar phases. However, all copper(II) were not mesogenic. The structures of mesophases were confirmed as hexagonal columnar phases (Colh) by powder XRD diffraction. X-ray single crystallographic analysis indicated the Pd center was coordinated as a square planar geometry and the Cu center was coordinated as a tetrahdral geometry.   In series II, a total numbers of sixteen twin dimers with structures similar to those in series I were prepared and studied. The formation of mesophases were found to be dependent of alkoxy chain density and/or the carbon length in alkyl spacer (m). All twin derivatives with two terminal alkoxy chains (n = C16H31) exhibited layer smectic phases and odd-even effect was also observed. All derivatives with an even-carbon spacer (m = 4, 6, 8, 10) formed SmC phases and other derivatives with odd-carbon spacer (m = 5,7) exhibited SmA (m = 5, 7). However, all dimers derivatives with four alkoxy sidechains (n = 12) and shorter spacers (m = 3, 5) exhibited hexagonal columnar phase.

Abstract This research utilizes the method of organic synthesis to put different amount of aminophenol into hydroxybenzoic acid or caffeic acid so as to produce a series of high yield of polyhydroxy benzamides (1~40).Through the following different activity tests, discussing the applied value of cosmetics.Ⅰ. The experiment of their ability to scavenge DPPH free radical, Ⅱ. The test of inhibitory activity of H2O2, Ⅲ. The activity test of inhibit Tyrosinase. The result of scavenging DPPH free radical by the polyhydroxy benzamides: The ability to scavenge DPPH free radical which is related to the amount of substitution of hydroxy groups and their positions. The more hydroxy groups substituted at the carboxylic acid benzene ring, the scavenging of DPPH free radical is more stronger, otherwise, the substitution of two hydroxy groups are at the ortho-position or para-position of carboxylic acid benzene ring, the ability of antioxidant is apparently more stronger. And the ability of antioxidant of polyhydroxy benzamides don’t have too many differences with Trolox (IC50 =13.90 μg/ml), the substition of hydroxy group at amino benzene ring doesn’t affect the whole ability of antioxidant apparently, but while the single hydroxy group at carboxylic acid benzene ring, they are apparently decrease to scavenge the ability of free radical, as a result, the hydroxy at amino benzene ring substitutes its function, without the hydroxy group, the ability of antioxidant is worst, but it upgrades its function while the hydroxy and amino are in the ortho-position or para-position. In the evaluation of polyhydroxy benzamides inhibit H2O2, both of them have better depressing effect and related to the amount of the substitution of hydroxy groups at the carboxylic acid benzene ring for the antioxidant activity are more stronger than Trolox (IC50 = 12.06 μg/ml), but a few of them is exception, (ex: IC50 = 53.96 μg/ml of compound 25, IC50 =45.77 μg/ml of compound 28 and IC50 =30.56 μg/ml of compound 33). The result of polyhydroxy benzamides for whitening, the activity evaluation of tyrosinase inhibitory, it has apparently effect on the caffeic acid, gallic acid and 2, 5-dihydroxybenzoic acid of amide derivatives (IC50 = 62.41~130.28 μg/ml), but some of the compounds show apparently the activity of tyrosinase inhibitory, (ex:IC50 = 71.70 μg/ml of compound 12 and 57.26 μg/ml of compound 24) inhibitory efficacy. Form the experiment, the compounds 20、24、34、37、39 and 40 of Poly- hydroxy benzamides have powerful activity to scavenge of DPPH free radical, inhibitory activity of H2O2 and tyrosinase, They are worthy to discuss the effective function which applied for anti-aging and whitening cosmetics.

We report the synthesis of halido Os(II) p-cymene complexes bearing bidentate chelating phenylazobenzothiazole (AZBTZ) ligands. Unlike the analogous phenylazopyridine (AZPY) complexes, AZBTZ-NMe2 is capable of both N,N-coordination to Os(II) and cyclometalation to form N,C-coordinated species. N,C-Coordination occurs via an azo nitrogen and an ortho carbon on the aniline ring, as identified by 1H NMR and X-ray crystallography of [Os(p-cym)(N,N-AZBTZ-NMe2)Cl]PF6 (1a), [Os(p-cym)(N,N-AZBTZ-NMe2)Br]PF6 (2a), [Os(p-cym)(N,C-AZBTZ-NMe2)Br] (2b), and [Os(p-cym)(N,C-AZBTZ-NMe2)I] (3b). The N,C-coordinated species is more stable and is not readily converted to the N,N-coordinated complex. Analysis of the crystal structures suggests that their formation is influenced by steric interactions between the p-cym and AZBTZ-NMe2 ligands: in particular, larger monodentate halide ligands favor N,C-coordination. The complexes [Os(p-cym)(N,N-Me2-AZBTZ-NH2)Cl]PF6 (4) and [Os(p-cym)(N,N-Me2-AZBTZ-NH2)I]PF6 (5) were synthesized with methyl groups blocking the ortho positions on the aniline ring, forcing an N,N-coordination geometry. 1H NMR NOE experiments confirmed hindered rotation of the arene ligand and steric crowding around the metal center. Complex 2b exhibited unexpected behavior under acidic conditions, involving regiospecific deuteration of the aniline ring at the meta position, as observed by 1H NMR and high-resolution ESI-MS. Deuterium exchange occurs only under acidic conditions, suggesting an associative mechanism. The calculated partial charges on 2b show that the meta carbon is significantly more negatively charged, which may account for the regiospecificity of deuterium exchange.

We have investigated the electrochemical, spectral, and kinetic properties of the synthesized triarylamines and their cation radicals and dications. The UV/Vis spectral changes for the formation of cation radicals and dication species of these compounds were successfully observed by repeated scan of the absorption spectra at fixed voltages below their half-wave potentials. The spectral changes for the regeneration of the cation radical and then the neutral species could be observed by resetting the voltage to 0.0 V (vs. Ag/AgCl) after the dicationic species was formed. These observations allowed us to investigate the kinetics of the whole redox processes for some triarylamines. We also found that the rates for the formation of radical cations and dicationic species of these compounds increased exponentially with increasing applied voltages. The kinetic data indicate that the rate constants (k) for the conversion are strongly dependent on the individual step, the applied potential, and the identity of the substituents. Moreover, linear Hammet plots were observed for the half-wave potentials of first redox couples and the absorption maxima (both neutral and cationic species) against the substituent constant (3)Theoretical calculations have revealed that the removal of the first and second electrons from these compounds comes mostly from the nitrogen atom and the phenyl rings, respectively. Dual chemiluminescence (CL) from the KIO4-luminol-Mn2+ system was originated from different CL pathways participated by various reactive oxygen species (ROS) such as O2-, •OH, and 1O2. It is interesting to examine how the cation radicals generated from derivatives of triarylamine affect the dual CL emission. In the presence of a strong oxidant KIO4 and a catalyst Mn2+, the formation of radical cations of triarylamines inhibited the first peak, but further enhanced the second peak. The resulting CL emission was used to determine the phenolic compounds such as dopamine, (+)-enpinephrine and flavones. These compounds are capable of reacting with ROS and radicals efficiently.

New aggregation induced emission materials have a wide range of applications and have been confirmed, but the AIE type of material has been published is still scarce. The material of pure organic compounds are particularly rare. Therefore, in this thesis, we have developed a series of new luminescent materials with AIE nature, that is tetra-phenyl or biphenyl N-substitute phthalimide, and used the simple route to do the synthesis. We also measure the fluorescence properties of the synthesized phthalimide compounds containing aromatic group, with the measure containing the absorption spectrum, emission spectrum and quantum yield. We also have compared the fluorescence properties in different substitute, containing various kinds of aromatic ring and the different functional groups. In this thesis, we try to explore the impact on the compounds properties in the polar and nonpolar solvents.

This research is based on using N-Phenyl-p-phenylenediamine (2ANI) as the reducing agent to rapidly convert electrospun silver ions into silver nanofibers by heat treatment. Polyacrylonitrile (PAN) used as the matrix material was mixed with silver nitrate (AgNO3) which was reduced into silver atoms by 2ANI in N,N-dimethyl-acetamide (DMAc). PAN/2ANI/Ag nanofiber composites were prepared via electrospinning process. The electrospun nanofiber composites were then treated at high temperature to obtain a highly conducting fiber since silver particles can expand and melted to connect with each other. The resistance can approach as low as 4Ω and the wire width is below 10 μm in this study. The influences of, silver nitrate concentration, heat treatment temperature, reaction time of the effect of resistance, and surface morphologies were analyzed by using FE-SEM, HR-TEM, XRD, TGA, Multi Probe Station after heat treatment.

Organic light-emitting materials have attracted considerable interest for recent years. In particular, aggregation induced emission (AIE) material have been focus of many recent studies, especially the effect of structural changes in organic light-emitting material. In this thesis, we introduce the AIE mechanism in detail. Based on the mechanistic understanding, we developed a series of new aggregation-induced emission compounds such as tetra (1-naphthyl) phenyl N-substituted phthalicamindes, which contain different substituents. Then, we explore the AIE effect of these compounds by measurement of fluorescence properties, absorption spectrum, emission spectrum and quantum yield. And we explore the solvent effect of these compounds.

This research is based on using N-Phenyl-p-phenylenediamine(2ANI) to obtain atomic silver from its ionic state and study on the effects different doping protonic acids on the morphology of the silver-composite product. In the presence of protonic acids in solvent, silver nitrate (AgNO 3 ) were reduced and the structural changes of educed silver in 2 hours and 24 hours was observed. From the POM, a linear silver fiber is been, and the FE-SEM micrographs reveal the silver fiber is in nano size. The effects of different types of acids and the concentration of 2ANI, and silver nitrate, ratio of solvent to acid, and solvents type on the obtained silver fibers were studied. The conjugated structure were also studied by UV-Vis spectra the 2ANI doped with protonic acids.

To take advantage of self-assembly to construct a variety of supramolecular architectures and polymeric networks with potential applications is a challenging in crystal engineering. In this thesis, we designed and synthesized an unsymmetrical pyridyl-amine ligand, N-(4-(4-aminophenoxy)phenyl)isonicotinamide (papoa), to react with CdX2 (X=Br, I)、HgX2 (X=Cl, Br) to investigate the anion and solvent effects in the reaction process. The complexes studied in this thesis contain [CdBr2(papoa)]n (1), [CdI2(papoa)]n (2a), [CdI2(papoa)]2•3(C2H5)2O2 (2b), [HgCl2(papoa)]2 (3), and [HgBr2(papoa)]2 (4), which are isolated and structurally characterized by X-ray diffraction studies. X-ray analysis reveals the formation of 0-D macrocyclic structures for 2b, 3, and 4, and 1-D double zigzag chains for 1 and 2a. The 0-D and 1-D frameworks can be extended into multidimensional structures by hydrogen bonds. In the structural frameworks each macrocycle includes CdX2 and HgX2 units, with roughly tetrahedral coordination geometries for Cd(II) and Hg(II) centers, and two papoa ligands. When CdI2 is reacted with papoa in the presence of different solvents, two different coordinated patterns for 2a and 2b can be obtained. 2a involves two papoa and three iodide anions, whereas 2b is composed of two papoa and two iodides. These Cd(II) and Hg(II) complexes display blue emission in the solid state, and can be probably assigned to an intraligand transition (IL).

This thesis includes two parts discussing the synthesis, structure andintermolecular interactions of metal complexes containing polydentate ligands. Part I. The reactions of the unsymmetrical N-Phenyl-N′-cyano-formamidine (HPhCNF) ligand with Cd(NO3)2 · 4H2O and Co(NO3)2 · 6H2O affordedtwo complexes of the type M(HPhCNF)2(NO3)2(THF), (M = Cd, 1 ; M =Co), 2 which were characterized by single-crystal X-ray diffraction method and elemental analyses.Both the metal center of complexes 1 and 2 adopt pentagonal bipyramidal geometry. The metal atoms were bonded to two nitrogen atoms of cyano group, four chealting nitrate oxygen atoms, and one oxygen atom of THF solvent group. In these two complexes, C-H---O and N-H---O hydrogen bonds were found to link the molecules. Part II. The reactions of 2-aminotkiazole (2-AT) with AgClO4, AgNO3,Ag2SO4, and Zn(OAc)2 · 2H2O afforded four new complexes of the types of [Ag(2AT)2ClO4], 3 [Ag(2AT)2NO3], 4 [Ag2(2AT)2(SO4)][Ag2(2AT)2](SO4)] · 2(CH3OH), 5 and Zn(OAc)2(2AT)2, 6. Their crystal structures were characterized by single-crystal X-ray diffraction method and elementalanalyses. In complexes 3 and 4, the silver metal centers adopt linear geometry that were bonded to two nitrogen atoms of 2-AT. The molecules adopting linear geometry were interlinked through N-H---O hydrogen bonds. Molecules in complexes 5 were linked through extensive Ag---S, Ag---O, Ag---Ag, S---S, S---O, O---O, hydrogen bondings, and π – π staking interactions. In complex 6, the zinc metal centers were bonded to two nitrogen atoms of two different 2-AT groups, one monodentate acetate and one chealting acetate anion, to form a distorted square pyramidal geometry. The molecules were linked through N-H---O hydrogen bonds and S---S interaction. In compounds 7 and 8, the protonated 2-Amino-2-thiazoline cations, [H(2A2T)]+ were interacted with nitrate and perchlorate anions through hydrogen bonds, forming 1-D hydrogen-bonded tapes. The eight complexes were characterized by single-crystal X-ray diffraction method and elemental analyses.

In the first part of this monograph, various chiral glyoxylic oximes were prepared to develop a new route to synthesize chiral α-amino amides, which are synthetic intermidiates of α-amino acids. The allylation of camphor sultam derived glyoxylic oxime ether by allyltributyltin in the presence of Lewis acids Zn(OTf)2, AgOTf, Sn(OTf)2 provided homoallylic α-amino amides, and Sn(OTf)2 emerged as the best Lewis acid when tested in allylation of various chiral glyoxylic oxime ethers. To continue the research in allylation of glyoxylic oxime ether, we studied allylation by using triallylaluminium. The reaction of triallylaluminium with chiral glyoxylic oxime ethers provided homoallylic amine products up to > 99% diastereoselectivity. In the following parts, we have investigated the scope of N-phenyl camphorpyrazolidinone in synthetic organic chemistry. When N-phenyl camphorpyrazolidinone derived α-keto amides employed in hydride reduction, the hydride reduction of aliphatic and aromatic α-keto amides provided corresponding α-hydroxy amides in excellent yields and very high level of diastereoselectivities.

In a preliminary study in our laboratory on the reaction between n-butyl bromide and sodium phenolate catalyzed by tetrabutyl ammonium bromide to prepare n-butyl phenyl ether, we found that a third liquid phase appeared apparently when we used polar chemicals, such as n-hexane and cyclohexane, as the solvent for organic reactant.In order to observe the formation condition of the third liquid phase and to elucidate the role it plays on the reaction, we carried out a series of experimental studies on the same reaction with n-hexane as the solvent. The experiment results reveal that the third liquid phase appears in all cases of our experiments. The reaction rate increases with increasing the amount of catalyst and increases at first then decreases with increasing the amount of sodium phenolate. The catalyst is in equilibrium among aqueous phase, oil phase and the third liquid phase. When a small amount of sodium phenolate is used, the reaction rate will first decrease sharply due to the disappearance of the third liquid phase and then increase sharply due to the appearance of the third liquid phase and a vast amount of increase of its catalyst with the amount of sodium hydroxide added.If the amount of sodium hydroxide added is too much, the reaction rate will gradually decrease due to high viscosity and low solubility of n-butyl bromide in the third liquid phase.On the other hand, when a large amount of sodium phenolate is added, the third liquid phase appears only when a large amount of sodium hydroxide has been added. Under such a circumstance, the reaction rate decreases sharply then increases slightly with increasing the amount of sodium hydroxide. When the amount of sodium phenolate added is small and that of sodium hydroxide is high,the reaction changes from pesudo-zero order to pesudo- first order.

This thesis has demonstrated high open-circuit voltage (VOC) organic photovoltaic (OPV) device by introducing a high ionization energy material bis(4-(N-(1-naphthyl)phenylamino)phenyl)fumaronitrile (NPA- FN) as the donor layer. Characterization of NPAFN was thoroughly studied by the ultraviolet-visible (UV-vis) spectroscopy, photoelectron spectroscopy, atomic force microscopy (AFM), and the model of space-charge limited current (SCLC). Devices comprised ITO/NPAFN/ C60 / 4-Hydroxy-8-methyl-1,5-naphthyridine aluminium chelate (AlmND3)/Al were optimized to the power conversion efficiency (PCE) of 2.02% under AM 1.5G simulated solar illumination (1-sun) through the optical manipulation and electrical property tuning. The significant improvement in VOC of ~1 V was ascribed to the high energy difference between the highest occupied molecular orbital (HOMO) of NPAFN (5.7 eV) and the lowest unoccupied molecular orbital (LUMO) of C60 (4.2 eV). Incident photon-to-electron conversion efficient (IPCE) results reveal that the contribution of carriers from NPAFN competed with that from C60, which implied not only high VOC but also effective extraction of photocurrent for the function of NPAFN. Device with such optimum structure was further analyzed in terms of the deposition of NPAFN. The performances under illumination and in the dark were studied. Morphological changes in different deposition rates indicated that the intermolecular interactions were considerably influenced during film deposition. The higher deposition rate of NPAFN resulted in the lower carrier mobility due to the weak molecular interaction, which was confirmed by the equivalent-circuit fitting and SCLC model. At the same time, the lower molecular interaction leaded to the higher VOC. Finally, the PCE was further improved to 2.3% at the NPAFN deposition rate of 0.5 nm/s. The OPV device was also investigated into the electroluminescent (EL) properties. With the same OPV structure, the device exhibited current efficiency of 0.11 cd/A at 100 mA/cm2. The EL spectrum implied that the electron might recombine with the hole in the NPAFN layer. The practical application of light-emitting photovoltaic device was studied as the function of the device reflectance. Compared to the conventional organic light-emitting device (OLED), the device based on NPAFN/C60 possessed the higher contrast due to the relatively low reflectance within the visible spectrum.
