Electron transfer from ethylenedithiotetrathiafulvalene (EDT-TTF) to photo-excited C60/C70 in polar and in nonpolar solvents has been investigated by laser flash photolysis. The transient absorption band of the triplet state of C60/C70 (3C60*/3C70*) was effectively quenched by EDT-TTF with the appearance of the absorption bands of C60.- /C70.-, showing that the electron transfer takes place from EDT-TTF to 3C60*/3C70* in polar solvents. Even in non-polar solvents, a small amount of C61.-/C70.- disappeared by back electron transfer to (EDT - TTF).+ with second-order kinetics, suggesting the formation of free radical ions. The radical ions disappeared with first-order kinetics in nonpolar solvent, indicating that the radical ions are present as contact ion-pair. In the presence of O2, the competition for the quenching of 3C60*/3C70* takes place between electron transfer from EDT-TTF and energy transfer to O2. Protonation reaction of C60.-/C70.- was also followed in the presence of appropriate proton source.
