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.

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.
