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。 Β-phenethylmethyldichlorosilane, diphenyldichlorosilane and N, N’-bis (dimethylchlorosilyl) tetramethylcyclodisilazane were used in the reaction of sodium metal in toluene Two kinds of Si-Si chain polymers containing Si-N tetrane ring were synthesized. These polymers have high molecular weight, low melting temperature, good solubility and thermoformability, and coated with solution to obtain a transparent film with certain strength, flexibility and elasticity. Organic ligands are added to the polymer solution and their UV spectra indicate that both form a CT complex.
