富勒烯化聚甲基苯基硅烷的合成及光电导性

C₆₀独特的结构和性能使其不仅具有重要的理论研究价值,而且在材料、生命科学等众多领域中显示出巨大的应用潜力^1,2].由于C₆₀在许多有机溶剂中溶解性差,因而改善其加工性能已成为实现C₆₀应用价值的关键.

Synthesis and Photoconductivity of Fullerenated Polymethylphenylsilane

The fullerenated polymet hylphenylsilane(C₆₀-PMPS)was synthesized by two meth-ods. Either PMPS was synthesized via Wurtz type reduced coupling reaction firstly and Then C₆₀-PMPS was synthesized by Friedel-Crafts type reaction;or C₆₀-PMPS was obtained by directcopolymerization of dichloromet hylpHenylsilane and C_60.The structure of each type of C₆₀-PMPS was characterized by a series of methods such as UV-Vis, GPC and IR.The results show that C₆₀bonds with The pendant benzene ring of PMPS in Friedel-Crafts type C₆₀-PMPS while C₆₀may in₂corporate into The main chain in The case of copolymerized C₆₀-PMPS.The photoconductivity measurement s show that The copolymerized C₆₀-PMPS has a good photoconductivity in contrast with pure PMPS and Friedel-Crafts C₆₀-PMPS which have hardly any photoconductivities.
