Zinc(II) meso-tetrakis(1-(3-sulfonatopropyl)-4-pyridino), Zn-TPSPyP/sup 0/, forms a complex with anthraquinone-2,6-disulfonate, AQS/sub 2//sup 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 AQS/sub 2//sup 2 -/ is bound to the micelles. The excited sensitizer decays to a long-lived triplet state (0.5 ms) and induces the reduction of AQS/sub 2//sup 2 -/. The micelles also function in the charge separation of the electron-transfer products. 22 references, 6 figures, 1 table.
