Photochemistry and sensitized evolution of hydrogen from water using water-soluble cationic porphyrins. Tetrakis(trimethylaminophenyl)porphyrinatozinc and its free base

Kuppuswamy Kalyanasundaram  

Abstract

Photophysical properties (fluorescence spectra, lifetimes, triplet–triplet absorption spectra, triplet lifetimes and quantum yields) and redox potentials have been measured for the free-base, Zn2+ derivatives of a cationic water-soluble porphyrin, tetrakis(trimethyl-aminophenyl)porphyrin [TAPP(4+)]; the values are similar to those of tetrakis(sulphonatophenyl)porphyrin, TPPS(4 –). The zinc porphyrin ZnTAPP undergoes facile photoredox reactions and also sensitizes H2 evolution upon visible-light photolysis in ‘sacrificial’ systems, albeit with a lower efficiency in comparison with tetrakis(4-methylpyridyl)porphyrin, ZnTMPyP.
