摘要
对富勒烯功能高分子材料的制备、表征及其性能研究已成为当前国际上的前沿领域之一。从合成角度考虑，以不同的方法对Ｃ６０ 进行高分子修饰可得到结构、性质各异的富勒烯高分子衍生物，对于研究如何更好地控制Ｃ６０ 高分子衍生物的结构，探讨有Ｃ６０ 参与的聚合反应的机理以及Ｃ６０ 在高分子衍生物中的作用无疑是很有帮助的。从应用角度考虑，Ｃ６０ 引入高分子中必将导致新型聚合物的产生。这些新型聚合物表现出许多独特而极具应用价值的功能行为，如光电导性能，导电性和非线性光学性质等。如何在温和条件下高选择性、高产率地合成可溶易加工的含富勒烯Ｃ６０ 的高分子衍生物是目前亟待解决的问题。
The systematic developments of synthetic methodologies for the functionalization of fullerenes have paved the way for the preparation of novel polymeric compounds of interest in the search of new materials with marvelous photoconductivity, electric and magnetic properties as well as nonlinear optical response over the past seven years. [60]Fullerene and its derivatives can be directly incorporated into a variety of polymers by copolymerization or grafting. The results show that covalent attachment of C 60 to specific polymers may allow combination of the splendid characteristics of fullerene with the outstanding properties of the polymeric matrix to generate new fullerene-based specialty polymer materials. However, owing to the identical physical and chemical environment of each carbon atom on the C 60 , a major problem during the synthesis of fullerene-containing polymers is how to prevent crosslinking.
