摘要: 采用β-苯乙基甲基二氯硅烷、二苯基二氯硅烷和N,N′-双(二甲基氯硅烷基)四甲基环二硅氮烷,在甲苯中与金属钠作用缩合成两种含Si—N四环的Si—Si链聚合物。这些聚合物分子量高、熔融温度低,溶解性及热成形性好,用溶液涂膜得到具有一定强度、柔性和弹性的透明薄膜。将有机配位体加入到聚合物溶液中,其紫外光谱表明两者形成了CT复合物。

Abstract: Polysilanes containing four membered rings with Si-Nbonds in the backbone were synthesized by cocondensation of methyl (β- phenethyl) dichlorosilane (or diphenyldichlorosilane ) and N,N'-bis-(chlorodimethylsilyl)tetramethylcylclodisilazane with sodium metal in toluene. The polymers possess higher molecular weights, lower softening points, better solubilities in common solvents. By casting the solution of each of the polymers in toluene on a glass plate, an elastic transparent film with fairly mechanical strength can be obtained. The polymers with some electron acceptors, such as(这里有图片19900418-406-1.gif)etc., can form C. T. complexes which show strong UVabsorption bands at a relatively low energy.

Key words: Methyl (β- phenethyl) dichlorosilane, Diphenyldichlorosilane Four membered rings with Si-N bonds, Polysilane
