Synthesis and electrochemical investigation of covalently linked porphyrin dimers containing a b-brominated subunit. Crystal structure of H2(tripp-tpp(Br8))H2 - Two new meso-tetraphenylporphyrin-type heterodimers containing a partly or completely b-brominated subunit were synthesized. These compounds and their zinc, copper, nickel and cobalt complexes were characterized by UV-visible spectroscopy, cyclic voltammetry and spectroelectrochemistry, showing the presence of low electronic interactions between the two subunits. One of the synthesized dimers, H2(tripp-tpp(Br8)H2, was characterized by a single-crystal X-ray investigation.Ou, Zhongping et al. | 2003

Synthesis of tetra(tricarbethoxy)- and tetra(dicarboxy)-substituted soluble phthalocyanines - Pd(II), Co(II), Cu(II) and Zn(II) phthalocyanines with a tricarbethoxyethyl substituent on each benzo group were prepared from 4-(1,1,2-tricarbethoxyethyl)-phthalonitrile. Transesterification occurred when the reaction was carried out in pentanol. Deesterification of the palladium complex resulted with tetra(1,2-dicarboxyethyl)phthalocyaninatopalladium. Its UV-vis spectrum in aqueous solution indicated dimeric and monomeric species at pHSener, M.Kasim et al. | 2003

Interaction of diatomic ligands with Fe(II)-meso-mono-4-pyridyl-tri-phenyl-porphyrinate. Spectral evidence of self-assembly in sublimed layers - Sublimed layers of Fe(II)-meso-mono-4-pyridyl-tri-phenyl-porphyrinate form two types of axial complexes with CO, NO and O2, ligands. In one of these, the 5th coordination site is occupied by the pyridyl group of an adjacent molecule indicating the self-assembly of FeMPyTPP in layers with formation of coordinatively linked oligomers.Kurtikyan, Tigran S. et al. | 2003

Syntheses and photochemical properties of a tribenzonaphtho-condensed porphyrazinatozinc complex - We report the synthesis of a zinc derivative of tribenzonaphthoporphyrazinato (Zn-tri-PcNc) obtained from 6-carboxymethyl-2,3-dicyanonaphthalene and phtalonitrile. This new phthalocyanine (Pc) compound has been characterized by 1H NMR, elemental analyses, IR and UV-vis. Steady state and time resolved spectral analysis revealed a fluorescence quantum yield and a fluorescence lifetime of FfPelisson, Marcelo M.M. et al. | 2003

Effects of pH and organic co-solvents on the oxidation of naphthalene with peroxosulfate catalyzed by iron(III) tetrakis(p-sulfonatophenyl)porphyrin - The catalytic oxidation of naphthalene using potassium monopersulfate and iron(III) tetrakis(p-sulfonatophenyl)porphyrin is influenced by solution forms, such as buffer pH and co-solvent types. The dimerization of FeTPPS and the electron donating character of co-solvents lead to differences in the oxidation efficiency.Kawasaki, Mikio et al. | 2003

Long-lived photoinduced charge transfer state of synthetically affable porphyrin-fullerene dyads - Porphyrin-fullerene dyads linked by bislactone moieties were studied optically using the transient displacement current technique. Efficient intramolecular electron transfer from porphyrin to fullerene with the lifetime of the charge transfer state on the order of a few nanoseconds was observed in low polarity solvents. Solvent polarity effect on the yield of charge separation and conformations in the charge transfer state are investigated in detail.Montforts, Franz-Peter et al. | 2003

The effects of catenation on the acidity constants of porphyrin (2)catenanes - The pKa values of the porphyrins in a series of porphyrin (2)catenanes are critically influenced by the degree of freedom and crowding in the interlocked subunits, which can move to alleviate the resulting coulombic repulsions in the monoacid and diacid forms.Gunter, Maxwell J. et al. | 2003

Electrochemical and resonance Raman studies of nitridomanganese(V) porphyrins in nonaqueous solution - A nitridomanganese(V) meso-tetrakis(4-pyridyl)-porphyrin was synthesized to probe the electron-withdrawing substituent effect of the porphyrin rings as compared to benzene rings in tetrakis(p-tolyl)porphyrin on the spectral and electrochemical properties. Notable effects of hydrogen bonding and axial ligands on the Mn-N triple bond were observed. The stretching frequency of the Mn-N triple bond is correlated with the pKa's of a series of pyridines.Jou, Jeng-Yi et al. | 2003

Highly brominated porphyrins: synthesis, structure and their properties - A facile synthesis of highly brominated copper(II)-porphyrin complex is presented. Its crystal structure features an unusual five-coordination at the Cu(II)-center with a saddle-shaped geometry. The free-base porphyrin and its metal complexes exhibit interesting electrochemical redox behavior.Bhyrappa, Puttaiah et al. | 2003
