摘要：

采用ESR技术对甲基紫精(MV2+)在三乙胺与C60的电子转移反应中的催化作用进行了研究. 反应体系无MV2+存在时, 三乙胺与C60并不发生电子转移反应, 得不到电荷的分离态; 在MV2+存在的条件下, 由三乙胺向C60分子的电子转移得以实现, 并检测到活泼中间体MV+•及电荷分离态C60-•, MV2+实质上起到催化剂的作用.

关键词: 电子转移反应, C60, 甲基紫精, 催化作用

Abstract:

The catalytic role of MV 2+ in the electron transfer reaction between C 60 and Et 3N was directly proved by means of ESR technique. The active radical intermediate produced during the catalysis was confirmed to be MV +• andC 60-•radicals. In contrast, without the presence of MV 2+ the process of the electron transfer can not proceed at room temperature any more.
