Fullerene derivative epoxy group deprotection method

Номер: CN102584746A
Автор: Yang Xiaobing, Ding Songtao, Ren Hongxuan, Fang He, Zhao Bin, Yang Bo
Принадлежит:

The invention relates to a 1, 3-dioxolane type fullerene derivative epoxy group deprotection method. A 1, 3-dioxolane type fullerene derivative, free radical absorbent iodine or C60 is taken as a raw material for removal reaction of an epoxy protecting group under illumination, so as to synthesize an epoxy peroxy fullerene derivative, and the thermal stability of the epoxy peroxy fullerene derivative is researched. The reaction has an important significance to follow-up functionalization of the peroxy fullerene derivative as well as the surface decoration. Through the adjustment to a decoration group, an energy contained insensitiveness additive having certain insensitiveness and contributing certain energy can be obtained, and the method can be widely applied to energy-contained materials.
