Abstract

Zinc(II) meso-tetrakis[1-(3-sulfonatopropyl)-4-pyridino]porphyrin, Zn-TPSPyP⁰, forms a complex with anthraquinone-2,6-disulfonate, AQS₂^2-. The porphyrin is statically quenched by the quinone acceptor in the complex structure. In the presence of CTAB micelles the complex is separated and AQS₂^2- is bound to the micelles. The excited sensitizer decays to a long-lived triplet state (0.5 ms) and induces the reduction of AQS₂^2-. The micelles also function in the charge separation of the electron-transfer products.
