Role of Ruthenium Oxidation States in Ligand-to-Ligand Charge Transfer Processes
(American Chemical Society, 2012-01)
We describe in this paper the properties of [RuII/III(bpy)2ClL]+1/+2 and [RuII/III(bpy)2L2]+2/+3. L = ditolyl-3-pyridylamine (dt3pya) is a redox active ligand related to triarylamines, which is very similar to 3-aminopyridine ...
Axial ligand influence on geometries, charge distributions and electronic structures of iron tetraazamacrocycle [Fe((II))TIM(X)(Y)](2+) complexes assessed by Density Functional Theory
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
We employed the Density Functional Theory along with small basis sets, B3LYP/LANL2DZ, for the study of FeTIM complexes with different pairs of axial ligands (CO, H(2)O, NH(3), imidazole and CH(3)CN). These calculations did ...
Synthesis, characterization, spectroscopic and electrochemical studies of donor–acceptor ruthenium(II) polypyridine ligand derivatives with potential NLO applications
(Elsevier, 2015)
In this work we report the preparation of six new donor–metal–acceptor (D–M–A) type complexes of
ruthenium(II) with the highly absorbing ‘‘chromophoric’’ ligand 4,40-bis(2-(4-methoxyphenyl)styryl)-
2,20-bipyridine, ...
Chiral ligand-exchange chromatography with Cinchona alkaloids. Exploring experimental conditions for enantioseparation of α-amino acids
(Elsevier Science, 2016-11)
The natural Cinchona alkaloid quinidine as chiral selector in chiral ligand-exchange chromatography was systematically studied. Chromatographic conditions for enantioseparation of twentya-amino acidswere first timestudied ...
Tuning of the Reorganization Energies by Innocent Co-ligands in Novel Mixed-Valent Dinuclear Ruthenium Complexes
(Pergamon-Elsevier Science Ltd, 2003-02)
Two novel mixed-valent ruthenium complexes, of formulae [(tpy)(bpy)RuII(pz)RuIII(edta)]+ and [(CN)4RuII(bpz)RuIII(edta)]3- (where tpy = 2,2′:6′,2″-terpyridine, bpy = 2,2′-bipyridine, pz = pyrazine, bpz = 2,2′-bipyrazine, ...
Estudo teórico da estrutura molecular e propriedades espectroscópicas de complexos polipiridínicos de Ru(II)
(Universidade Federal de Minas GeraisUFMG, 2015-02-27)
The study of the photophysical properties of polipyridyl Ru(II) complexes is of great interest in a series of aplications, such as cancer therapy. [Ru(bpy)2(L)]2+ (with L = bpy: 2,2-bipyridine; phen: 1,10-phenantroline; ...
Complexos de ferro e manganês com derivados da base de Schiff salen e ligantes carboxilatos
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM QUÍMICA, 2019-06-28)
Salen Schiff base complexes have been highlighted both as antitumor agents,
catalysts and modified electrodes. Thus, the present work has the objective to synthesize
new iron(III) and manganese(III) complexes containing ...
Strongly luminescent, highly ionic europium in a lanthanum diphenylphosphinate matrix
(2013-01-01)
A series of insoluble, chemically inert and thermally stable compounds La1-xEux(DPP)3 (x = 0.50, 0.20, 0.10, and 0.050; DPP = diphenylphosphinate) was synthesized and characterized by elemental and thermogravimetric analysis, ...

A comparison of charge-transfer mechanisms at rotated disk electrode for biomimetic binuclear and tetranuclear oxo-manganese complex in aqueous solution
(Elsevier B.V., 2015-01-30)
Many high-valence multinuclear mu-oxo-bridged manganese complexes have been synthesized to mimic the active site of the natural enzymes. The electrochemical and kinetic parameters were determined for two mimicking complexes ...
