1. Study of the Reactivity of complex ions cis-[Ru (bpy)2(L) (NO)]n+ where L = imidazole, 1-metilimidazole, thiourea and sulfite / Estudo da Reatividade dos Ãons complexos cis-[Ru(bpy)2(L)(NO)]n+ onde L=imidazol, 1-metilimidazol, tioureia e sulfito
We carried out studies of chemical reactivity, electrochemistry and photochemistry of complexes cis-[Ru(bpy)2(L)(NO)](PF6)n, where L = imidazole, 1-methylimidazole, thiourea and sulfite. Were chosen, therefore, two ligands being donors and two with ligands that act as -recipient and the results indicated that the nature and strength of these

2. Estudo eletroquÃmico e fotoquÃmico da liberaÃÃo de Ãxido nÃtrico nos Ãons complexos do tipo trans-[Ru(NH3)4LNO]3+, onde L=tionicotinamida e isotionicotinamida / Electrochemical and photochemist study of the nitric oxide release in Ãons complex of the type trans- [Ru (NH3) 4LNO] 3+, where isotionicotinamida and L=tionicotinamida
Neste trabalho, inicialmente realizou-se a sÃntese e caracterizaÃÃo dos Ãons complexos precursores: trans-[Ru(NH3)4TioSO4]+ e trans-[Ru(NH3)4IsotioSO4]+. Posteriormente realizou-se a sÃntese, caracterizaÃÃo e o estudo fotoquÃmico dos nitrosilo complexos: trans-[Ru(NO)(NH3)4Tio]3+ (I) e trans-[Ru(NO)(NH3)4Isotio]3+ (II). Objetivando, portanto, a modul

3. AvaliaÃÃo espectroscÃpica da substituiÃÃo sistemÃtica de molÃculas de Ãgua coordenadas por ligantes β-dicetonas em complexos com Ãons lantanÃdeos
In this work, lanthanide complexes with β-diketones (2,4-pentanedione and trifluoroacetylacetone) and β-keto esters (etil 4,4,4,-trifluoro-2,4- pentanedione) ligands have been synthesized. The complexes showed general formulas: [Ln(acac)(H2O)6]Cl2, [Ln(acac)2(H2O)4]Cl, [Ln(tfa)(H2O)6]Cl2, [Ln(tfa)2(H2O)4]Cl e [Ln(eta)2(H2O)4]Cl. The compounds were

4. SÃntese e estudo espectroscÃpico de complexos de Ãons lantanÃdeos incorporados em materiais hÃbridos orgÃnicos-inorgÃnicos
In this work two new europium and gadolinium b-diketonate complexes, [Ln(btfa)3(4,4 -bpy)(EtOH)] (Ln = Eu, Gd; 4,4 -bpy = 4,4 -bipyridine; btfa = 4,4,4- trifluoro-l-phenyl- 1,3-butanedione), were prepared and incorporated into a organicinorganic hybrid material. The general formulae of these complexes were confirmed by X-rays single crystal data and elementa

5. Sistemas Trinucleares Contendo Ãons LantanÃdeos
Aiming to develop new ligands capable to coordinate most of one lanthanide ions, this work shows the synthesis of trinuclear systems for photonics applications and characterization by elemental analysis, spectroscopic methods (infrared, electronic absorption and NMR of 1H and 13C). A particular study, about the new compounds synthetized, shows the substituti

6. Desenvolvimento de dispositivo fotÃnico para monitoramento de metais poluentes em recursos hÃdricos
In this work they were studied some properties of a polymeric of the class of the superabsorbents (SAP), that is used broadly in the industry of products of personal care. This polymeric one that is a derived of the acrylic acid formed by reticulation of nets crosslink, an excellent agent complexante was shown, for presenting in its structure groups amids an

7. Novos desenvolvimentos e aplicaÃÃes de mÃtodos de quÃmica quÃntica para compostos de coordenaÃÃo com Ãons lantanÃdeos
Theoretical studies on lanthanide compounds were performed, and divided into three parts: (i) generalization of the Linderberg-Seamans equations for an s-p-d-f basis set; (ii) study of the ligand-to-lanthanide ion charge transfer transitions (LMCT) with the ZINDO98 program using the INDO/S semiempirical hamiltonian and (iii) a study of point charge and charg
