Photoinduced electron transfer processes between fullerenes (C_(60) /C_(70)) and triphenylamine (TPA) have been studied by nanosecond laser flash photolysis. Quantum yields (Φ_(et)) and rate constants (k_(et)) of electron transfer from TPA to excited triplet state of fullerenes (C_(60)/C_(70)) 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 (C_(60)/C_(70)) and radical cations of TPA appear.
