Zinc(II) mexo-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 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.
