摘　　要：在运用ＥＳＲ 方法对Ｃ６０ 与一系列萘胺化合物的光诱导电子转移反应过程的研究中发现，对于不同萘胺衍生物，其反应性随化合物分子结构的变化而改变．由于空间位阻作用和氮原子上的孤对电子与芳环的共轭作用，使得萘胺比脂肪胺较难给出电子，而连接两个芳基的Ｎ苯基取代萘胺则更难给出电子．ESR method was used to study processes and intermediates of photoinduced electron transfer (PET) reaction between C\-\{60\} and a series of aromatic amine compounds. The results show that PET reactivity of C\-\{60\} 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 C\-\{60\} and N phenyl naphthylamines was inhibitted. \;
