C60负离子化学的研究进展

Progress in the Chemistry of Fullerene Anions

中性的C60是很强的缺电子体,主要和亲核试剂进行化学反应。与之不同的是C60经还原生成负离子后,由缺电子变为富含电子,具有很强的亲核性质,可与亲电试剂进行反应。由于这种电子结构的变化,C60负离子进行的反应从机理至产物均有可能与中性富勒烯不同,从而丰富了富勒烯的反应方式和富勒烯产物的类型。结合我们的工作综述了C60负离子化学的研究进展,对丰富富勒烯化学、扩展富勒烯衍生物的种类及制备方法具有一定意义。

Unlike neutral C60, which is an electron-deficient molecule and reactive towards nucleophiles, C60 anions are electron-rich species and reactive towards electrophiles. Owing to the different electronic structures between the C60 anion and neutral C60, it is likely that C60 anions may undergo a different reaction mechanism compared with neutral C60 during the reactions, which may lead to the formation of novel fullerene derivatives. Herein, the progress of the chemistry of C60 anions is reviewed in order to get a better understanding of fullerene anions and fullerene chemistry. As the review indicates, it is necessary to further investigate the chemistry of fullerene anions since many aspects of it are not well understood at the current stage.
