Повний текст джерелаTriazenes are a class of compounds characterized by the presence of a diazoamino functional group (N=N N) showing remarkable ability to support the stereochemical requisites of a wide variety of metal transition complexes. They act as versatile ligands in coordination chemistry when deprotonated and have relevant biological and synthetic porperties. This work presents the synthesis and investigation of molecular and crystal structure of a new series of monotriazenes [3-(4-phenyldiazenyl)-1-(2-fluorophenyl)triazene (2b); 1-(2-chlorophenyl)-3-(4-phenyldiazenyl)triazeno (2c), 1-(2-bromophenyl)-3-(4-phenyldiazenyl)triazene (2d); 3-(4-phenyldiazenyl)-1-(2-iodophenyl) triazene (2e); 1,3-bis-(3-methoxy-4-methylbenzoate)triazene (2g)] and substituted 1,4-bis (phenyltriazenyl)butanes, C6H5N(H)=N-N(CH2)4-N=NN(H)C6H5, [1,4-bis(4-ethyl-benzoato triazenyl) butane (5a), 1,4-bis(2-fluorophenyltriazenyl)butane (5b), 1,4-bis(2-clorophenyltriazenyl)butane (5c), 1,4-bis(2-bromophenyltriazenyl)butane (5d), 1,4-bis(2-iodophenyltriazenyl)butane (5e), 1,4-bis(4-amidophenyltriazenyll)butane (5f)]. The insertion of groups on phenyl rings attached to the triazene chains makes the environment significantly more interesting coordination providing the supramolecular array through noncovalent intermolecular interactions and self-organizatinal units of primary molecule. The metal ions used for complexation are salts of Ni2+, Cu2+ and Pd2+ and they were chosen due to the attracting biological relevance, magnetic properties, catalytic yielding. Nine metal complexes unpublished were synthesized [trans-[PdII(C6H5NNC6H4NNNC6H4Cl)2(C5H5N)2] (3c) [(PdII (R1R2C6H3NNNC6H3R1R2)(PPh3)2Cl) DMSO] [R1 = 4-C(O)OCH3, R2 = 3-OCH3] (3g) [CuII (RC6H5NNN(CH2)4NNNC6H5R)]2 [R = C2H5C(O)O (6a), R = F (6b), R = NH2C(O) (6f)], [NiII (RC6H5NNN(CH2)4NNNC6H5R)]2 [R = F (7b) R = Cl (7c) R = Br (7d) R = NH2C(O) (7f)]. The synthesis and characterization of these compounds is justified by the exploration of the reactivity, the coordinative behavior and by the understanding of the interactions between different ligands and metal centers. The structural analysis of the synthesized compounds by X-ray diffraction on single crystal in the solid state were performed for characterization of interactions in the crystal. Thus, a thorough understanding of the relationship between the crystal structure and supramolecular organization is analyzed. Besides the structural analysis of compounds, elemental analysis CHN, infrared, nuclear magnetic resonance and ultraviolet-visible spectroscopies and mass spectrometry were also carried out for characterization. The physical chemical properties were investigated through thermogravimetric analysis and magnetic susceptibility.
Triazenos são importantes membros da família de compostos nitrogenados de cadeia aberta, caracterizados por conter o grupo funcional [N═N─N] e apresentam diferentes propriedades de coordenação a metais de transição. São compostos fracamente ácidos e quando desprotonados atuam como ótimos ligantes na química de coordenação apresentando grande importância sintética e biológica. Nessa tese, foi inicialmente desenvolvida a síntese de uma série inédita de compostos triazenos monocatenados [3-(4-fenildiazenil)-1-(2-fluorofenil)triazeno (2b); 1-(2-clorofenil)-3-(4-fenildiazenil)triazeno (2c); 1-(2-bromofenil)-3-(4-fenildiazenil)triazeno (2d); 3-(4-fenildiazenil)-1-(2-iodofenil)triazeno (2e); 1,3-bis(3-metoxi-4-metilbenzoato)triazeno (2g)] e de compostos triazenos biscatenados derivados do 1,4-bis(feniltriazenido)butano, C6H5N(H)N=N-(CH2)4-N=N-N(H)C6H5, [1,4-bis(etil-4-benzoatotriazenil) butano (5a); 1,4-bis(2-fluorofeniltriazenido)butano (5b); 1,4-bis(2-clorofeniltriazenido)butano (5c); 1,4-bis(2-bromofeniltriazenido)butano (5d); 1,4-bis(2-iodofeniltriazenido)butano (5e); 1,4-bis(4-amidofeniltriazenido)butano (5f)]. A inserção de grupamentos substituintes nos anéis fenila na cadeia triazenídica tornam o ambiente de coordenação significativamente mais interessante, propiciando o aumento da ocorrência de interações intermoleculares não covalentes e impondo a auto-organização de unidades moleculares primárias no estado sólido. Os metais escolhidos para complexação foram sais de Ni2+, Cu2+ e Pd2+ em virtude de atraírem atenção como objeto de estudos relacionados com medicina, propriedades magnéticas e catálise obtendo-se como resultados deste trabalho nove complexos metálicos inéditos [trans-[PdII(C6H5NNC6H4NNNC6H4Cl)2(C5H5N)2] (3c); [(PdII(R1R2C6H3NNNC6H3R1R2)(PPh3)2Cl)·DMSO] [R1 = 4-C(O)OCH3, R2 = 3-OCH3] (3g); [CuII(RC6H5NNN(CH2)4NNNC6H5R)]2 [R = C2H5C(O)O (6a); R = F (6b); R = NH2C(O) (6f)] ; [NiII(RC6H5NNN(CH2)4NNNC6H5R)]2 [R = F (7b); R = Cl (7c); R = Br (7d); R = NH2C(O) (7f)]. A síntese, e a caracterização desses novos compostos estão relacionadas à exploração da reatividade, ao comportamento coordenativo e a compreensão das interações entre os diferentes centros metálicos e os ligantes. Efetuou-se um estudo estrutural no estado sólido para a caracterização das interações presentes nas estruturas cristalinas dos compostos sintetizados e a ferramenta utilizada foi à difração de raios X em monocristal. Dessa forma aprofundou-se a compreensão da relação entre a estrutura cristalina e sua organização supramolecular. Além do método de difração de raios X de monocristal os compostos foram caracterizados por espectroscopia de infravermelho, espectroscopia de ressonância magnética nuclear, 1H e 13C, espectroscopia ultravioleta e visível, espectrometria de massas e análise elementar CHN. As propriedades físico-químicas foram investigadas através de análise termogravimétrica e susceptibilidade magnética.

A series of monomeric copper complexes that allow for the tuning of the emission properties is reported. Luminescence lifetimes up to 150 [mu]s are observed in benzene solution at ambient temperature, which are comparable to the lifetimes of the longest-lived previously reported copper luminophores. These complexes also exhibit quantum yields up to 0 = 0.70 at 298 K. The results of time-dependent density functional theory (TDDFT) calculations indicate emission from a triplet state in all cases. The calculations also successfully correlate the energy of the transition from this triplet state to the energy of the observed emission. Such luminescence from a first-row metal is highly unusual, especially when considering the phosphine-based ligand framework used.

Повний текст джерелаEsta Tesis Doctoral se centra en el estudio de catalizadores moleculares para la oxidación de agua basados en cobre y níquel, ya que su gran abundancia y su bajo coste los hace potenciales candidatos para su uso en sistemas catalíticos. A pesar de esto, hoy en día hay una importante carencia de información con respecto a sus mecanismos de reacción y los factores que determinan su actividad. Por ello, en primer lugar, se desarrollan nuevos catalizadores moleculares basados en cobre como centro metálico. El estudio mecanístico de dichos catalizadores revela el importante rol que tiene la oxidación del ligando en el ciclo catalítico a la hora de controlar el sobre-potencial de la reacción. Al mismo tiempo, en colaboración con el grupo del Profesor Maseras (ICIQ) se descubre un nuevo mecanismo para la formación del enlace oxígeno-oxígeno que opera en diferentes tipos de catalizadores de cobre. Este nuevo mecanismo sin precedentes permite redefinir el escenario mecanístico para la oxidación de agua. Posteriormente, se realiza el diseño de nuevos ligandos con diferentes propiedades redox que permiten estudiar los factores que influyen en la actividad y el mecanismo de reacción. Esto proporciona información relevante para el diseño de nuevos catalizadores más activos, estables y eficientes. También se aborda la inmovilización de los catalizadores desarrollados sobre electrodos basados en grafeno. De esta forma se descubre el papel esencial que tiene la deslocalización de electrones en orbitales π, que permite incrementar la cinética de reacción por más de dos órdenes de magnitud. Finalmente, el conocimiento generado en cobre se intenta expandir para su aplicación en catalizadores de níquel. Esto permite estudiar el carácter lábil de los complejos de níquel en medios básicos, que determina la presencia de dos mecanismos de operación basados en especies moleculares y óxidos de níquel respectivamente.
This Doctoral Thesis focuses on the study of molecular catalysts for water oxidation based on copper and nickel since their high abundance and inexpensive character make them potential candidates for their use in catalytic systems. Despite that, there is a current lack of information regarding their reaction mechanism and the factors that determine their activity. Therefore, we first develop new molecular catalysts based on copper as metal center. Their mechanistic study reveals the essential role that the ligand oxidation has in the catalytic cycle as tool to control the reaction overpotential. In collaboration with Prof. Maseras group (ICIQ) a new mechanism for the oxygen-oxygen bond formation is found to operate in different copper catalysts. This unprecedented mechanism allows us to redefine the mechanistic scenario in water oxidation. Later on, the design of new ligands with different redox properties is addressed. That allows to study the factors that have influence on the activity and reaction mechanism and provide valuable information for the design of more active, stable and efficient new catalysts. Moreover, the immobilization of the molecular catalyst on the surface of graphene-based electrodes is also studied. We discover the essential role of the π-delocalization in increasing the reaction kinetic by more than two orders of magnitude. Finally, the knowledge developed with copper complexes is applied in nickel catalysis. This allows to study the labile character of nickel complexes in basic media that determine the presence of two different operating mechanism based on molecular species and nickel oxides respectively.
