Photophysical properties and aggregation behavior of transition metal tetraphenylporphyrin tetrasulfonate complexes in microheterogeneous media

Abstract

This paper considers the influence of various surfactants and polyelectrolytes on the photophysical properties and the aggregation state of transition metal complexes of meso-5,10,15,20-tetrakis-(4-sulfonatophenyl)porphyrin (MeTPPS). Porphyrin transition metal complex aggregation stability in acidic medium is also compared for a number of metal cations. The mechanism of J-aggregate formation and the nature of porphyrin-surfactant interactions in microorganized systems are discussed in details. © ISUCT Publishing.
