虽然早在1958年Natta等就报道了用TiCl_4-AlR_3催化体系可使乙炔聚合,但所得聚合物为不溶不熔粉末,不能加工成型,未能引起广泛的兴趣。七十年代初,白川用高浓度的Ti(OBu)_4-AlEt_3催化体系,首次得到了均匀的聚乙快膜。随后美国宾夕法尼亚大学的研究小组与白川合作,对聚乙炔膜进行p~-,n~-型掺杂,使其电导率增加约12个数量级,成为目前室温电导率最高的有机高分子导体。这一研究成果引起了人们极大的注意,成为当前有机导体研究的重要方向。近年来人们对聚乙炔的结构、电导及掺杂机理等进行了一些较为深入的研
Although Natta et al. Reported that acetylene can be polymerized with TiCl 4 -AlR 3 catalytic system as early as 1958, the resulting polymer is insoluble and insoluble powder and can not be processed and formed, which has not attracted much interest. In the early seventies, Shirakawa with a high concentration of Ti (OBu) _4-AlEt_3 catalytic system, for the first time get a uniform fast polyethylene film. Subsequently, the research group of the University of Pennsylvania cooperated with Shirakawa to p - -, n - - type doping of polyacetylene film, which increased the conductivity by about 12 orders of magnitude and became the highest conductivity polymer organic conductor at room temperature. This research has aroused great attention and become the current direction of organic conductor research. In recent years, people on polyacetylene structure, conductance and doping mechanism carried out some more in-depth research
