説明

Quenching rate constants (kq) of triplet C70 by electron donors have been measured by laser flash spectroscopy in benzonitrile and 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 diffusioncontrolled rates in the solvents used. The quenching rate constants of the triplet C70 were fairly similar to those of triplet C60 reported by Foote et al., and the coincidences of the rate constants can be ascribed to the practically same values of their triplet energies and reduction potentials between C60 and C70.
