    • A polysilane of Formula [I] or [II]: ##STR1## (wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6, R.sup.7, R.sup.8, R.sup.9, R.sup.10, R.sup.11, R.sup.12, R.sup.13 and R.sup.14 denote independently hydrogen, alkyl, aryl, alkenyl, alkynyl, silyl, and amino groups. R.sup.1 and R.sup.2, R.sup.3 and R.sup.4, R.sup.5 and R.sup.6, R.sup.7 and R.sup.8, R.sup.13 and R.sup.14, R.sup.10 and R.sup.11 can form a ring with the silicon bonded to each group. m is 0 or 1. n is an integer.);and a method for synthesizing the polysilane of Formula [I] or [II] in which a small-ring polysilane is reacted (in a solvent) with an organolithium reagent, and then treated with silanes possessing a leaving group. The resulting polysilanes have a homogeneous molecular weight distribution and are useful as a functional polymer for nonlinear optical materials and electroconductive polymers.
    • 式[I]或[II]的聚硅烷:其中R1,R2,R3,R4,R5,R6,R7,R8,R9,R10,R11,R12, R13和R14独立地表示氢,烷基,芳基,烯基,炔基,甲硅烷基和氨基,R1和R2,R3和R4,R5和R6,R7和R8,R13和R14,R10和R11可以形成环 硅键合到每个基团,m为0或1.n为整数。 和其中使小环聚硅烷与有机锂试剂反应的式[I]或[II]的聚硅烷的方法,然后用具有离去基团的硅烷处理。 所得聚硅烷具有均匀的分子量分布,并且可用作非线性光学材料和导电聚合物的功能性聚合物。
