摘要

The electron transfer between triethanolamine (TMA) and methylviologen(MV2+) was photosensitized by water-soluble meso-tetrakis (4-dimethylsulfonatopylanilino)porphyrins and meso-tetrakis (4-trimethylanilino) porphyrins excited in their triplet state by visible light in DMSO solution containing 20%, V/V water at room temperature. The kinetic parameter A, photo-inductive lame t(i) and initial reaction rate V-o are applied to measuring the photosensitivity of photosensitizers.
