C_(60)的聚合反应是一项十分有意义的研究课题。“珍珠项链”式的C_(60)聚合物将具有优良的导电和非线性光学性能,有可能成为新型功能高分子材料。自Yeretzian等人于1992年采用激光蒸发C_(60)膜率先在气相中实现C_(60)聚合以来,这一领域的研究一直方兴未艾。但总体来看,采用激光等手段尚不能得到宏观量的结构规整的聚合物。1994年瑞士科学家Pekker等人采用金属钾与C_(60)高温蒸气的反应,在特定的温区得到聚合度逾100000的C_(60)线性聚合物,表明钾对于
The polymerization of C_ (60) is a very significant research topic. “Pearls necklace” type C 60 polymer will have excellent conductive and nonlinear optical properties, it may become a new type of functional polymer materials. Since Yeretzian et al. (1992) adopted the C 60 film of laser evaporation to achieve C 60 polymerization in the gas phase, the research in this field has been in the ascendant. However, on the whole, macroscopic structured polymers can not be obtained by means of lasers. In 1994, the Swiss scientist Pekker et al. Used the reaction of metal potassium and C 60 hot steam to obtain the C 60 linear polymer with a polymerization degree of more than 100,000 in a specific temperature range,
