laser flash photolysis experiments. The distance between unpaired electrons in the triplet CS state was determined by the EPR spectrum to be 9.1 Å, which agreed with the distance between a zinc atom of the porphyrin and a carbon edge of C60 in the crystal structure of ZnP-C60. The rate constants of photoinduced electron transfer and back electron transfer of H2P-C60 and ZnP-C60, which were determined
