Abstract: ESR method was used to study processes and intermediates of photoinduced electron transfer (PET) reaction between C₆₀ and a series of aromatic amine compounds. The results show that PET reactivity of C₆₀ and amines changes with the variation of molecular structure of naphthylamine derivatives. Because of the delocalization and the steric hindrance of aromatic ring, it is more difficult to give out an electron from N-atom for naphthylamines than that for fatty amines. Furthermore, PET between C₆₀ and N phenyl naphthylamines was inhibitted.
