Photoinduced electron transfer processes between fullerenes (C₆₀/C₇₀) and N, N, N', N'-tetra-(p-methylphenyl)-4, 4'-diamino-1, 1'-diphenyl ether (TPDAE) have been studied by nanosecond laser flash photolysis. Quantum yields and rate constants of electron transfer from TPDAE to excited triplet state of fullerenes (C₆₀/C₇₀) in benzonitrile have been evaluated by observing the transient absorption bands in the near-IR region where the excited triplet state,radical anion of fullerenes (C₆₀/C₇₀) and radical cations of TPDAE appear.
