| Abstract | The electron-transfer reactions between azurin and the triplet as well as the radicals of several water-soluble metalloporphyrins (ZnTPPS, ZnTPPC, and ZnTMPyP where TPPS is tetrakis(sulfonatophenyl)porphyrin, TPPC is tetrakis(carboxyphenyl)porphyrin, and TMPyP is tetrakis(N-methylpyridyl)porphyrin) have been studied by two different photoexcitation schemes. The second-order rate constant varies from 1.7 × 108 to 5.5 × 108 M-1 s-1 (μ = 0.5 M, pH 7, 25°C) within the wide range of driving force (0.49-1.47 eV) covered in the experiment. A reorganization energy λ12 of about 1.1 eV and a maximum bimolecular electron-transfer rate kmax of 3.8 × 109 M-1 s-1 were obtained by analyzing the data according to the theory of Marcus. © 1987 American Chemical Society. |
