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.

    The cation radical, N*+, was prepared by adding bromine, dissolved in methylenchloride, to a solution of N in benzonitrile (initial concentration, 0.5 mM) under argon atmosphere in a glass apparatus attached to the EPR cell. The EPR spectrum of N*+ was taken at room temperature by a Varian E-102 spectrometer.Google Scholar
