Abstract

Fourier transform EPR spectroscopy was employed in studying the electron transfer (ET) reaction and the quenching mechanisms of the photoexcited triplet state of C60 as electron acceptor and N,N,N′,N′-tetramethylbenzidine (NTMB) as electron donor in benzonitrile solution. The ET reaction product, the cation radical NTMB•+, interacts with 3•C60, leading to photoinduced electron polarization of NTMB•+ via triplet-doublet mixing mechanism combined with triplet mechanism. The quenching of 3•C60 and the polarization behavior of NTMB•+ are discussed.
