Rate Correlation of Photoinduced Electron Transfer to C70

Abstract

Abstract Quenching rate constants (kq) of triplet C70 by electron donors have been measured by laser flash spectroscopy in benzonitrile and in acetonitrile-benzene (1 : 4). A plot of kq values versus free energy change for the electron transfer to 3C70 gives a fairly good correlation with rate constants calculated from the Rehm-Weller equation if corrected the diffusion-controlled rates in solvents used.
