Pełny tekst źródłaNowadays, chemistry represents a general tool for accessing (synthesis), controlling (parameters influence) and understanding (study of properties) the material. This is allowed by two possible approaches: the "Top-down" and "Bottom-up". The first approach is a key to nanotechnology. The second approach consists in assembling small systems, with intrinsic properties, to build up macro system with interesting properties. This concept is generally termed as: "from mo/ecu/es to material” and in this context, supramolecular chemistry plays a crucial rote. The present work examines the synthesis and properties of dithiolene systems bearing metal ions and lanthanides. The first chapter is a general introduction on dithiolene chemistry and lanthanides. The second chapter deals with the synthesis and characterisation of supramolecular systems based on neutral dithioiene-like ligands. Ln this chapter importance of non-covalent interactions is discussed. The third chapter concerns the reactivity of these neutral dithiolen like ligands towards d10 transition metals (CU1, Hg11, AU1). This chapter will describe the synthesis of supramolecul complexes and their spectroscopic properties. The fourth chapter deals, with the reactivity of the ligands with lanthanide (Nd, Eu, Gd, Tb, Er) and the characterisation of Ln3+ -dithiolene complexes. The discussion will be oriented on the energy transfer process taking place in these coordination compounds ("Antenna Effect")

Pełny tekst źródłaIt was the aim of this work, to assess the potential of p-tert-Butyltetramercaptotetrathiacalix[4]arene (H4(MTC[4])) to create multinuclear complexes with soft metal ions of d10 electron configuration. In contrast to the more known p-tert-Butylcalix[4]aren, H4(MTC[4]) offers extended possibilities for the coordination of metal ions at the thioether groups. While this work was initially inspired by the function of Cu(I) and Zn(II) ions in biological systems, the metal ions, which were incorporated into the Calixarene, were soon expanded by Ni(II), Ag(I) and Au(I) ions. Through their different preferred coordination geometries, these metal ions could yield new information about coordination modes of H4(MTC[4]). In experiments with copper(I) ions the complex [(Ph3PCu)4(MTC[4])] and the hexamer [Cu4(MTC[4])]6 were synthesized and characterized. [Cu4(MTC[4])]6 consists of a unique, supramolecular hollow Cu24S48 cage structure. The [Cu4(MTC[4])] units are connected by Cu2S2 motivs, which display extraordinary short Cu···Cu distances. An investigation by NMR spectroscopy indicated that the cavities of [Cu4(MTC[4])] in solution can hold acetonitrile or methane molecules. In experiments with silver(I) ions, the molecular structures of the compounds [(Ph3PAg)2AgH(MTC[4])], [(Ph3PAg)4AgCl(MTC[4])] and [(Ph3PAg)4(MTC[4])] were determined. In these compounds H4(MTC[4]) exhibits a similar coordination behaviour towards Ag(I) ions as it does towards Cu(I) ions. In experiments with gold(I) precursors it was possible to control how many gold(I) ions were coordinated by H4(MTC[4]). The complexes [(Ph3PAu)2H2(MTC[4])], [(Me3PAu)3H(MTC[4])] and [(Me3PAu)4TlCl(MTC[4])] were synthesized and studied. Due to their free thiol functions, they are potential precursors for the synthesis of heterometallic complexes.

Pełny tekst źródłaThe purpose of this work was the synthesis of N,N'-diphosphanyl-functionalized NHC ligands andtheir coordination chemistry. The novel stable and rigid tridentate N,N'-diphosphanyl-imidazol-2-ylidene was synthesized and experimental and computational information on its stability weregained. It served as a unique platform for the synthesis of novel mono-, di-, tri-, penta-, hexanuclear complexes with the coinage metals (Cu, Ag and Au), exhibiting rare structural features. The mono- and dinuclear complexes with one or two dangling P-donors provided rational access to heterotrinuclear complexes. All these coinage metal complexes have short metal-metalseparations, indicating the presence of d10-d10 interactions, and display excellent luminescentproperties. Partial or complete transmetallation of the homotrinuclear Cu or Ag complexes withPd(0) precursors led to hetero-trinuclear complexes with d10-d10 interactions. In addition to itsbridging behavior, this ligand also showed its chelating behavior in Pd or Cr(III) complexes. Thelatter displayed superior performance in ethylene oligomerization than the Cr(II) complexes andgave mostly oligomers

Pełny tekst źródłaThe elaboration of organic light emitting diodes (OLEDs) is a technological challenge of this early century. In order to optimize the efficiency of these devices, luminescent transition metal complexes can be incorporated in the emitting layer. In this context, coordination chemistry of d10 metal complexes was studied for the preparation of phosphorescent homo- and heteroleptic compounds starting from N- and P- ligands. Some of these complexes show excellent properties for the elaboration of light emitting diodes. Furthermore, coordination chemistry of d10 metal allows the preparation of different supramolecular structures. Starting from a copper (I) complex and different nitrile ligands, it is possible to obtain coordination polymers and macrocyclic compounds. These structures were characterized systematically in the solid state by X-ray crystallography and solution by NMR and UV-vis spectroscopy. The preparation of fullerene-rich nanostructures is another topic of our research group to elaborate advanced materials. In the context of this work, dendritic branches incorporating fullerene units were used in order to functionalize supramolecular assemblies prepared from copper(I) complexes, or to synthesize organooxotin nanoclusters surrounded by six dendritic branches from condensation of a carboxylic acid and a stannic acid

Pełny tekst źródłaLa trasformazione ossidativa di gruppi funzionali costituisce una delle reazioni fondamentali della chimica organica ed è alla base di moltissimi processi sintetici. Si tratta di un settore che è oggetto di un continuo lavoro di ricerca, indirizzato sia alla risoluzione di problemi sintetico-applicativi che alla comprensione dei meccanismi che operano in tali processi il cui interesse è così vasto da includere reazioni che avvengono anche in sistemi biologici. Negli enzimi, così come nei catalizzatori artificiali, la presenza di metalli in elevato stato di ossidazione permette l'attivazione di acqua ossigenata (H2O2) e di idroperossidi alchilici (RO2H) consentendo l’ossidazione di diversi substrati organici. Sia negli enzimi che nei sistemi artificiali particolare importanza riveste l’intorno chimico della specie reattiva metalloperossidica responsabile del trasferimento di ossigeno. I leganti al centro metallico, siano essi di natura proteica o costituiti da molecole di sintesi, sono in grado di aumentare non solo la stabilità e la reattività ma anche la capacità di stereoselezione del centro reattivo. Tuttavia, si trovano in letteratura numerosi esempi di come la reattività, la stabilità e la stereoselezione di processi sintetici catalizzati da complessi con leganti polidentati vengano ampiamente influenzati anche dalla presenza di additivi, o leganti monodentati per lo più basici, in seguito alla loro interazione con il metallo. L’influenza che leganti polidentati e co-leganti monodentati possono avere sulla reattività di numerosi sistemi catalitici è parte degli argomenti trattati nel primo capitolo di questa tesi di dottorato. In particolare abbiamo voluto indirizzare la nostra attenzione verso processi reattivi, soprattutto di tipo ossidativo, che vengono accelerati in seguito all’azione sia di leganti polidentati che di co-leganti monodentati. I numerosi esempi che sono stati riportati su questo argomento, tratti dalla recente letteratura, sono stati suddivisi all’interno di due classi di fenomeni: la “ligand accelerated catalysis” (LAC) e la “co-ligand accelerated catalysis” (CO-LAC). Nella LAC, secondo la definizione di Sharpless, l’aggiunta di un legante chirale polidentato induce la formazione, tramite scambio di legante, di un nuovo complesso metallico dotato di una aumentata reattività che spesso si accompagna anche ad una aumentata stereoselettività. Nella CO-LAC invece, l’aggiunta di un legante monodentato chirale o achirale, induce una modificazione della reattività del complesso metallico senza che vi sia scambio di legante. Numerosi esempi di CO-LAC prevedono l’utilizzo di leganti monodentati basici. Durante questo dottorato, abbiamo potuto constatare che il processo di trasferimento di ossigeno verso il metil p-tolil solfuro catalizzato da un complesso polisilosanico di V(V) recanti sostituenti iso-butilici in presenza di CHP come ossidante primario viene accelerato, anche di 24 volte, a seguito dell’aggiunta di basi di Lewis in quantità confrontabili con quelle del catalizzatore. Nel Capitolo 2 i dati sperimentali riportati evidenziano l’esistenza di una corrispondenza tra accelerazione osservata del processo e natura elettron donatrice della base di Lewis usata. Più elettron ricca è la base di Lewis maggiore è la reattività del sistema e, probabilmente a causa delle migliori capacità coordinanti del co-legante, minore è la quantità di base di Lewis necessaria per avere l’effetto massimo. Calcoli computazionali condotti hanno dimostrato come la coordinazione di basi di Lewis al vanadio inducano variazioni di distribuzione elettronica con aumento di densità elettronica all’ossigeno della specie reattiva metalloperossidica coinvolto nel trasferimento di ossigeno e contemporanea diminuzione della stessa a livello del centro metallico con conseguente stabilizzazione dell’intermedio reattivo. Lo studio sugli effetti delle basi di Lewis in processi di trasferimento di ossigeno a solfuri organici è stato esteso anche verso un’altra classe di leganti ossia le trifenolammine. Nel Capitolo 3 sono stati investigati processi catalitici di ossidazione del metil p-tolil solfuro per mezzo di cumilidroperossido come ossidante primario in presenza di otto complessi ammino tri-fenolati di metalli d0 [Sc(III), Ti(IV), Zr(IV), Hf(IV), V(V), Nb(V), Ta(V), Mo(VI)]. La reattività e la selettività di questi processi, sia in assenza che in presenza di una base di Lewis forte come il dimetilesil-N-ossido è stata determinata sperimentalmente. I dati sperimentali ottenuti sono stati correlati con i valori di elettronegatività di Sanderson e tramite studi teorici sono state tratte delle delucidazioni sulle caratteristiche della specie reattiva metalloperossidica. I dati sperimentali raccolti e i calcoli teorici ci hanno permesso di proporre un meccanismo generale per spiegare l’attivazione della specie perossidica e la sua reattività. Nel Capitolo 4 sono descritti i complessi ammino tri-fenolati di ossovanadio(V) come modelli funzionali e strutturali di aloperossidasi, grazie alla loro geometria trigonale bipiramidale e alla loro abilità nel catalizzare efficacemente sia le solfossidazioni così come la bromurazione e la clorurazione del trimetossibenzene. In particolare, nell’ossidazione di solfuri, usando perossido d’idrogeno come ossidante primario, sono state ottenute con rese quantitative in prodotto con alta chemoselettività, anche in presenza dello 0.01% di catalizzatore, con TON fino a 9900 e TOF fino a 8000 h-1. Nel caso della bromurazione si sono ottenuti TON pari a 1260 e TOF fino a 220 h-1 usando fino allo 0.05% di catalizzatore. Nel Capitolo 5 viene riportata una serie di strategie di sintesi per la formazione di un nuovo legante trisilanolico polisilossanico recante lunghe catene perfluorurate come sostituenti.

The self-organization of small molecules into helical structures could be found easily in living system. There are several sophisticated inorganic helicates have been developed. We aimed to introduce the hydrazone group to link polypyridyl binding domain, it plays two roles; both binding, and bridging unit, it also could be deprotonated to modulate the electronic coupling in multinuclear system. A family of novel polypyridyl type multi-binding domains ligands containing hydrazone linker were synthesized successfully, after complexed with Ag(l) or Cu(I) respectly, gives double helicates only, including dinuclear helicates, [Ag2(m-Ph-M-(Bpy)2)2](X)2, [Ag2(Bpy-(M-Pz)2)2](Z)2, [Ag2(Bpy-(M-Thio)2)2](Z)2, [Ag2(Bpy-(H-MThio)2)2](Z)2, trinuclear helicates, [Ag3(Py-M-(Bpy)2)2](X)3, [Ag3(Py-M-(Bpy)2)2](Y)3 [Ag3(C2-M-(Bpy)2)2](Z)3, [Ag3(C2-Ph-(Bpy)2)2](Z)3, [Ag3(Bpy-(H-M2Py)2)2](Z)3, [Cu3(Bpy-(H-M2Py)2)2](Z)3, [Ag3(Bpy-(M-Pz)2)2](Z)3, and finally a unique petanuclear helicate [Ag5(Bpy-(HC2H-Bpy)2)2](Z)5, (X=ClO4, Y=PF6, Z= CF3SO3). Solid state structures of complexes list above were confirmed by Xray diffractometry.The composition and Solution structures were also examined by FAB, ESI Mass and NMR method (COSY,NOESY), the results confirmed the double helix structure is maintained in the solution state. The self-recognition process and cooperative phenomena were studied by NMR and spectrophotometric experiments including UV-Vis,NMRand ESI titration, for helicates [Ag2(m-Ph-M-(Bpy)2)2]2+, [Ag3(Py-M-(Bpy)2)2]3+ , they express highly positive cooperation in individual ligand and self-recognition between ligands. The self-assembling process and reaction mechanism were investigated by means of sytematic measurement of step-wise and overall stability constant

This thesis can be divided into two subjects: I. Synthesis and structures of linear metal chain complexes. II. Photoluminescent properties of d10 metal complexes. I. Synthesis and structures of linear metal chain complexes The linear tri- and penta-nuclear metal chain were helically surrounded by four organic ligands(dpa-, tpda2-) to perform a wire-like structure. Trinuclear metal chain NiII and CoII complexes [M3(dpa)4X2] were synthesized by improved method, and axial position(X) was substituted to different axial ligands to research the property changes. Extending to pentanuclear metal chain complexes, the newly developed ligand, H2tpda, was used to form [M5(tpda)4X2] successfully. The axial ligands were also substituted to provide a serial model to research metal-metal interactions by x-ray structure determinations, magnetic properties(by SQUID), and x-ray absorption spectrum(by synchrotron radiation beam line). II. Photoluminescent properties of d10 metal complexes. Both d10 metal clusters using phenylacetylide ligand and d10 dinuclear metal complexes have interesting photo-luminescent properties. The photoinduced electron and energy transfer, possible photocatalyzed reaction and energy exchange of those compounds were characterized and discussed according to their absorption and emission spectra. Host-guest interaction study was approached by attaching luminescent d10 metal clusters to the peripheral appendages of polyazamacrocycles and crown ethers as supramolecular host. The x-ray structures of these d10 metal complexes were also provided.

The research focus in this thesis is classified into three parts. The first part is to study the structure, spectroscopic and photophysical properties of the trinuclear complex, [(8-QNS)2 Au(AuPPh3)2]BF4 1 (8-QNS = quinoline-8-thiolate). 1 is structurally characterized by the single crystal X-ray diffraction study, showing two intramolecular gold(I)•••gold(I) interactions (3.0952(4) and 3.0526(3) Å), where two molecules of 1 are further aggregated into a novel hexanuclear supermolecule, (1)2, via a close intermolecular gold(I)•••gold(I) contact of 3.1135(3) Å. In addition to the interesting structural property of 1, it also shows a dramatic solvent effect dependent on the solvent polarity. Second part is to utilize the designed pyridyl amides as bridging ligands for the construction of gold(I) supermolecules. When compared with the literature and free ligands, the emissions of these gold(I) supermolecules is tentatively assigned to a π → π* of PPh3 mixing with a Au → PPh3 transition. Third part includes synthesis and characterizations of a series of inorganic- organic Cd(II) coordination polymers 7 - 11. Py2S (4,4’- dipyridyl sulfide), 4-pytaH [(4-Pyridylthio)acetic acid] and PL3 (N1, N3, N5- tri(pyridin-4-yl)-isophthalamide) are chosen as bridging ligands to synthesize coordination polymers with different Cd(II) salts. 7, 8 and 9 form different polymeric structures due to different counteranions and solvent systems. 10 is formed as a 1-D polymer, but is further hydrogen- bonded to lead to the formation of a 2-D structure. 11 is formed as a 3-D coordination polymer with a channel structure. The luminescence properties of these coordination polymers are also investigated.

This thesis includes two parts discussing the synthese, structures and interactions of d10 metal complexes containing polydentate nitrogen ligands. Part I. The reactions of N,N′-di(pyridin-2-yl)oxalamide (L1), N,N′-di(pyridin-2-yl)succinamide (L2), N,N′- di(pyridin-3-yl)oxalamide (L3) and N,N′- di(pyridin-2-yl)adipamide (L4) with Ag(I) , Cd(II) , Hg(II) and Zn(II) metal salts afforded dinuclear and one-dimensional complexes, which have been fully characterized by EA and IR analysis and single-crystal X-ray diffraction. The dinuclear complexes [Ag2(L1)(CH3CN)6](SbF6)2, 1, Ag2(L1)(CH3CN)2(CF3CO2)2, 2, and Ag2(L1)(CH3CN)2(p-TsO)2, 3, (p-TsO- = p-toluenesulfonate), and 1-D polymeric chains [Ag(L1)(CH3CN)(CF3SO3)]n, 4, {[Ag2(L2)2(p-TsO)](p-TsO) • 2CH3CN}n, 5, {[Ag(L2)](SbF6) • CH3CN}n, 6, {[Ag(L3)](SbF6)•DMF}n, 7, {[Ag(L3)](PF6)}n, 8, {[Ag(L4)](BF4) • CH3CN}n, 9, {[Ag(L4)](PF6)}n, 10, and {[Ag(L4)](SbF6) • CH3CN}n, 11 form supermolecular structures through π-π stacking and weak Ag---O or Ag---F interactions. The 1-D helical chains of {[Cd(L1)(H2O)2](ClO2)2 • (CH3)CO}n, 12, are linked through π – π stacking interactions and N-H---O及C-H---O hydrogen bonds to form a 3-D supramolecular framework, and those of [HgCl2(L1)]n, 13, [HgBr2(L1)]n, 14, and the dinuclear Hg2(L1)(NO3)2, 15, are interlinked through π – π stacking interactions and various hydrogen bonds. The 1-D polymeric chains of [ZnBr2(L3) • DMF]n, 16, [ZnI2(L3) • DMF]n, 17 and [HgBr2(L3) • DMF]n, 18, are linked by their DMF molecules through the hydrogen bonds, while the molecules of the dinuclear Hg2I4(L3)2, 19 interact each with other through π – π stacking interactions and hydrogen bonds to form 3-D supramolecular frameworks. Similarily, the 1-D chains [Cd(L4)(ClO4)2]n, 20, and the dinuclear complexes, Hg2Br4(L4), 21 and Hg2I4(L4), 22 form 3-D nets through π – π stacking interactions and various hydrogen bonds. Part II. The amino-pyrimidine ligands, 2,4,6-triaminopyrimidine (L5) and 2-amino-4-methoxy-6-methylpyrimidine (L6) reacted with Ag(I) metal salts to form the complexes {[Ag2(L5)2(ClO4)](ClO4) • CH3OH}n, 23, {[Ag(L5)](p-TsO) • CH3OH}n, 24, [Ag4(L5)4(p-TsO)2](p-TsO)2 • 6DMF, 25, {[Ag2(L6)2(SO4)]•6H2O}n, 26,{[Ag(L6)](BF4)}n, 27, [Ag(L6)2](ClO4), 28, {[Ag(L6)2](PF6)}n, 29, [Ag(L6)(CF3CO2)]n, 30, and {[Ag(L6)](CF3SO3)}n, 31. All compounds have been characterized by spectroscopic methods and their structures determined by X-ray crystallography. The Ag(I) atoms of 23 and 24 are bridged by the L5 ligands to form 1-D polymeric infinite chain structures, and 0-D tetranuclear complex. The molecules of 23 – 25 are interlinked through weak C-H---π, π – π stacking and Ag---O interactions. The 1-D chains 26, 27, 30 and 31, and the molecules of the 0-D of 28 and 2-D grids of 29, are interlink through π – π stacking interactions and hydrogen bonds to form 3-D frameworks.

In this thesis,the ligand: 2,6-(diphenylphosphino)pyridine was used to obtain three Cu(I),Ag(I),Au(I) isostructure metal complexes.These complexes form a metallomacrocycle,which has an open cavity and should therfore be capable of binding a second, different ion.The host complex [(PNP)3Au2](ClO4)2 feature a red shift in the emission spectrum when guest ion was added, such as Cu(I),Ag(I) metal ion.And a character of down field shift in 31P NMR spectrum.A series of phenylacetylide-metal complexes contain tridentate ligand were synthesised.The metal-metal distance were short because of the metal-metal interaction. There are a red shift effect in solid state emission spectrum compare to the emission spectrum in solution,which was arise from the metal- metal interaction.We also successful synthesed a new ligand H2tpda(H2tpda=N,N''-bis(pyridine)-2,6- diaminopyridine),and [H2tpdaCoCl2],linear pentnickle complex [Ni5(tpda)4Cl2] were also synthesed.

Diphenyl(2-pyrrolyl)phosphine, Pyrr2P, which is a bidentate ligand, reacted with the group 11 metal ions to from dimeric compounds of the types [Au2(Pyrr2P)2] (3), [AuAg(Pyrr2P)2] (4) and [AuCu(Pyrr2P)2] (5). Their aurophilicity and metallophilicity with regard to the distances between two metal ions and the influence of luminescent properties were investigative. For compound 3, the Au-Au distance is 2.8865(5)~2.8745(5) ?? while in compounds 4 and 5, the Au-M distances are 2.8353(7) ? (M = Ag) and 2.7890(13) ? (M = Cu) respectively. Structures of 3 and 4 show head-to-tail coordination mode and structure 5 is head-to-head. The NMR spectra have been investigated for all three compounds. The Ag-P chemical shift and coupling constants in compound 4 are δ 0.23 (J1107Ag-31P = 567.0Hz, J1109Ag-31P = 656.1Hz). Their luminescent properties are also dependent on the metal-metal interaction or inter-molecular interaction. Compound 5 absorbs the visible light (424 nm) and emits the light-green color (546 nm). In this thesis, we also used the DFT calculation to describe each energy gap for 3, 4 and 5.

The research focus in this thesis is classified into three parts. The first part includes synthesis and characterization of a series of inorganic-organic d10 (Zn2+, Cd2+ and Hg2+) coordination polymers (1)—(5) with pyridyl-amide ligands, (L1-L3). Compounds (1)—(5) have been structurally characterized by single crystal X-ray diffraction studies, consisting of the frameworks of one-dimensional chains. The crystal packing of compound (4) is built up by the interwoven chains, where the micropore (8.5Å x 8.5Å) shows selective sensing for volatile organic compounds (VOCs) in size, aromaticity and hydrogen-bonding ability. Second part is to synthesize the luminescent Au(I) compounds (6)—(9) with sodium 1,4,7,10-tetraoxa-13-azacyclopentadecane-13-carbodithioate (NaCS2), and the X-ray crystal structures of compound (6) and (9) have been determined. The interesting structural, spectroscopic and photophysical properties of compound (6)—(9) are compared and discussed in this part. The excited states of these compounds are mostly due to S→Au charge-transfer transition because of the strong σ donor strength of thiolates. The host-guest recognition study has been performed on compound (10) in the third part. The luminescent host has been demonstrated to differentiate among alkali, transition metal, and lanthanide ions, showing interesting molecular-recognition events.

In this thesis,the three tetradentate ligands : 2-tolylsulfonyl- amido-7-hydroxy-1,8-naphthyridine(I),2,7- tolylsulfonylamido-1,8- naphthyridine(II),2,7-bis( diphphenylphosphino)-1,8-naphthyridine (III) was used to obtain polynuclear metal complexes.The two tri- nuclear metal complexes in which there are long distance between metal ions was obtained by using ligand I to react with Cu(II) and Co(II) respectively.As for ligand II, a trinuclear Cu(I) metal complex with red luminescence and a dinuclear Au(I) metal complex with green luminescence was synthesized. The latter can be regarded as a inorganic host to catch a guest ion such as Cu(I) which will let the color of luminescence change from green to red.The ligand III reacting with Cu(I) and Ag(I) ions gave linear trinuclear metal complexes. The Cu(I) ion was added as a guest ion to the analogous Au(I) dinuclear complex of ligand III for acquiring a host-guest supramolecular.It will induce the bleach of emission origined from host complex by the Cu(I) ion. The three Au(I)-Cu(I) heteronuclear metal complexes was synthesized by using pyrazolate anion as a bridge ligand.The shoter distance between Au(I) and Cu(I) ions than that in similar Pt( II)-Cu(I) heteronuclear complex shows the stronger attractive force existing in heternuclear d10 metal ions than in homonuclear d10 metal ions.In these heteronuclear complexes, the tetranuclear Au(I)-Cu(I) metal complex have a low-lying emissive state which was assigned as a cluster center excited state.

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.

Pełny tekst źródłaThe present work had as objective the accomplishment of batch tests of anaerobic biodegradability of effluents from the first stage of kraft pulp bleaching (D0), rich in recalcitrant and potentially inhibitory compounds (AOX). The effects on the removal of AOX and on the production of methane were evaluated by applying several conditions in the anaerobic treatment of the effluent D0: applied organic load; addition of a co-substrate; addition of ashes as a supplement and application of an enzymatic pre-treatment to D0. Thus, the use of two different organic loads of D0 (3 and 2 g-CQOs·L-1) was studied, with AOX removals of 70.6 and 74.2 %, removals of CODs of 47.5 and 26.2 % and CH4 production of 121.7 and 193.9 mL-CH4 initial·g-COD-1, respectively. Addition of acetate and glucose led to AOX removals of 52.6 and 70.4 %, respectively, COD removals of 76.2 and 42.9 %, and methanization efficiencies of 335.0 and 124.0 mL- CH4 initial·g-COD-1. It was concluded that the AOX removal was maximized in the reactor fed with 2 g-COD·L-1 of D0. Anaerobic digestion of the filtered and unfiltered D0 mixture with CA5, CTB and lime sludge ash was studied, was obtained AOX removals between 62.0 and 74.4 %. In reactors fed with unfiltered D0 mixture neutralized with CA5 ashes and CTB ashes occurred the production of 166.3 and 157.2 mL-CH4 initial·g-COD-1, respectively. The use of CA5 and CTB ashes appears to have been advantageous in the removal of AOX and have no significant effects on CH4 production. The addition of enzymes, and CA5 and CTB ashes was studied. It has been found that under the conditions applied, the use of enzymes and ashes together does not appear to have the desired effect. In the study of the Archaea and Bacteria communities it was verified that the application of D0 as substrate seems to have led to changes in the composition of the communities present in the biological sludge. In conclusion, anaerobic digestion has been shown to have potential for the treatment of D0, namely the removal of AOX, and to produce CH4
