It is known that polysilanes display unique characteristics such as UV absorption, photo-, and electroluminescence due to σ-conjugation of the Si-Si main chain. We have been studied the preparation of new water-soluble polysilane, the energy transfer and radiative properties of polysilanes, and energy-matched counterparts. And, it was found that photo-oxidation during irradiation an ultraviolet light was suppressed by using water-soluble polysilanes and embedding them inside sol-gel glass matrices. However, there are problems for the preparation of watersoluble polysilanes, because Wurtz type reaction usually gives only a low yield. So, it is important to improve the way for the synthesis of water-soluble polysilanes.We have interested in the use of commercially available dodecaphenylcyclopentasilane(DPCPS). DPCPS was treated with Li in tetrahydrofuran to give ring opening intermediate ; α, ω-dilithiododecaphenylpetasilane. Reaction of the intermediate with an equimolecular amount of d … More ichlorodimethylsilane afforded cyclic polysilanes, resulted from intramolecular cyclization reaction, and a small amount of low molecular-weight polymer. On the other hand, the treatment of the intermediate with an equimolecular amount of 1,2-dichlorotetramethyldisilane gave higher molecular weight polysilane co-polymer as a result of predominant intermolecular reaction.The obtained co-polymer was successfully converted into water-soluble polysilane derivative by successive Friedel-Crafts chloromethylation and quaternary ammonium reaction.The intermolecular energy transfer from conductive poly(m-hexoxyphenyl)phenylsilane was utilized for electroluminescence(EL) of perylene (blue), coumarin 6 (green), 4-(dicyanometliylene)-2-methyl-6-(p-dimethylammostyryl)-4H-pyran and Zinc tetra-phenylporphyrin (red). A white EL was also observed by mixing the four dyes. Photo-oxidation during irradiating a ultraviolet light was suppressed by synthesizing water-soluble polysilanes and embedding it inside sol-gel glass matrices. These results imply that polysilanes have a possibility to open new fields of optical application. Less

众所周知，由于 Si-Si 主链的 σ 共轭，聚硅烷表现出独特的特性，例如紫外吸收、光致发光和电致发光。我们研究了新型水溶性聚硅烷的制备、聚硅烷的能量传递和辐射性能以及能量匹配的对应物。并且发现，通过使用水溶性聚硅烷并将其嵌入溶胶-凝胶玻璃基质内，可以抑制紫外线照射期间的光氧化。然而，水溶性聚硅烷的制备存在问题，因为Wurtz型反应通常产率较低。因此，改进水溶性聚硅烷的合成方法非常重要。我们对市售十二苯基环戊硅烷(DPCPS)的使用感兴趣。 DPCPS在四氢呋喃中用Li处理，得到开环中间体； α, ω-二锂硫代十二苯基五硅烷。该中间体与等分子量的二氯二甲基硅烷反应，通过分子内环化反应得到环状聚硅烷和少量低分子量聚合物。另一方面，用等分子量的1,2-二氯四甲基乙硅烷处理中间体，由于分子间反应占主导地位，得到了较高分子量的聚硅烷共聚物。通过连续的Friedel-Crafts氯甲基化和季铵反应，所得共聚物成功转化为水溶性聚硅烷衍生物。 利用导电聚（间己氧基苯基）苯基硅烷的分子间能量转移来电致发光（EL）苝（蓝色）、香豆素 6（绿色）、4-（二氰基亚甲基）-2-甲基-6-（对二甲基氨基苯乙烯基）-4H-吡喃和四苯基卟啉锌（红色）。通过混合四种染料还观察到白色EL。通过合成水溶性聚硅烷并将其嵌入溶胶-凝胶玻璃基质中，可以抑制紫外线照射期间的光氧化。这些结果意味着聚硅烷有可能开辟新的光学应用领域。较少的
