The photoinduced electron‐transfer reaction of N, N, N', N' ‐tetra‐( p ‐methylphenyl)‐4,4'‐diamino‐1,1'‐diphenyl ether (TPDAE) and fullerenes (C 60 /C 70 ) by nanosecond laser flash photolysis occurred in benzonitrile. Transient absorption spectral measurements were carried out during 532 nm laser flash photolysis of a mixture of the fullerenes (C 60 /C 70 ) and TPDAE. The electron transfer from the TPDAE to excited triplet state of the fullerenes (C 60 /C 70 ) quantum yields and rate constants of electron transfer from TPDAE 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 TPDAE are expected to appear.
