The electron transfer between triethanolamine (TEOA) and methylviologen (MV²⁺) was photosensitized by water-soluble meeo-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 time t_i and initial reaction rate V_o are applied to measuring the photosensitivity of photosensitizers.
