(AMER CHEMICAL SOC, 2011)
Investigação das propriedades fotofísicas de porfirinas meso substituídas com complexos de RuII e estudo da interação com biomoléculas
(Universidade Federal de Santa MariaBrasilQuímicaUFSMPrograma de Pós-Graduação em QuímicaCentro de Ciências Naturais e Exatas, 2019-08-05)
The objective of this work was to investigate the photophysical properties of two porphyrins whose syntheses are already reported in the literature: meso-tetra(4-pyridyl)porphyrin tetra-ruthenated free-base (H2RuTPyP) and ...
On an Electrode Modified by a Supramolecular Ruthenium Mixed Valence (Ru(II)/Ru(III)) Diphosphine-Porphyrin Assembly
(AMER CHEMICAL SOC, 2009)
Three novel polymetallic ruthenium (III) meso-tetra(4-pyridyl)porphyrins containing peripheral ""RuCl(3)(dppb)"" moieties have been prepared and characterized. The X-ray structure of the tetraruthenated {NiTPyP[RuCl(3)(dppb)](4)} ...
Redox properties of ruthenium nitrosyl porphyrin complexes with different axial ligation: Structural, spectroelectrochemical (IR, UV-Visible, and EPR), and theoretical studies
(American Chemical Society, 2008-08)
Experimental and computational results for different ruthenium nitrosyl porphyrin complexes [(Por)Ru(NO)(X)]n+ (where Por2- = tetraphenylporphyrin dianion (TPP2-) or octaethylporphyrin dianion (OEP2-) and X = H2O (n = ...
Novel manganese (III) porphyrin containing peripheral [RuCl(dppb)(X-bipy)](+) cations [dppb=1,4-bis(diphenylphosphino) butane and X = -CH3, -OMe, -Cl]. X-ray structure of the cis-[RuCl(dppb)(bipy)(4-Mepy)]PF6 complex
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
New tetraruthenated manganese (III) porphyrins were synthesized and characterized (P-31 NMR, cyclic voltammetry, UV-Vis). This new system presents four units of cationic ``[RuCl(dppb)(X-bipy)](+)``. The electrochemical and ...
