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 ...
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 ...
Electrochemical studies of copper(II) complexes with Schiff-base ligands
(PERGAMON-ELSEVIER SCIENCE LTD, 2002-01-15)
The electrochemical reduction of copper(II) complexes with salen Schiff-base ligands derived from ethylenediamine or (R,R) or (S,S)-1,2-diphenylethylenediamine and 5-methoxy, 5-bromo and 5-nitrosalicylaldehyde have been ...
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, ...
Temperature-dependent permeability of the ligand shell of pbs quantum dots probed by electron transfer to benzoquinone
(American Chemical Society, 2015-07)
This paper describes an increase in the yield of collisionally gated photoinduced electron transfer (electron transfer events per collision) from oleate-capped PbS quantum dots (QDs) to benzoquinone (BQ) with increasing ...
Searching for drug leads targeted to the hydrophobic cleft of dengue virus capsid protein
(2022-01-01)
We synthesised and screened 18 aromatic derivatives of guanylhydrazones and oximes aromatic for their capacity to bind to dengue virus capsid protein (DENVC). The intended therapeutic target was the hydrophobic cleft of ...
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 ...
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, ...
