摘要：
Fourier transform EPR spectroscopy was employed in studying the electron transfer (ET) reaction and the quenching mechanisms of the photoexcited tripIet state of C-60 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*C-60, leading to photoinduced electron polarization of NTMB.+ via triplet-doublet mixing mechanism combined with triplet mechanism. The quenching of C-3*(60) and the polarization behavior of NTMB.+ are discussed.
