| 摘 要： | 制备了3种双（二甲基硅基）取代的含硅单体化合物,即1,4-双（二甲基硅基）苯、4,4′-双（二甲基硅基）联苯、9,10-双（二甲基硅基）蒽,并将上述化合物分别与4,4′-双（乙炔基）联苯在RhCl（PPh3）3/NaI催化下进行硅氢加成反应,制备相应的硅桥联共轭聚合物.进一步对聚合物单体的光物理性质研究发现,由于硅甲基对构型的影响,聚合物对单体均呈现一定的荧光增强现象.利用对硝基苯胺作为淬灭剂,聚合物在淬灭剂极低浓度时（10-6 mol/L）,依然具有良好的淬灭性.

| Abstract: | Three kind of silicone-containing monomers, 1,4-bis （dimethylsilyl） benzene, 4,4＇-bis （dimethylsilyl） biphenyl and 9,10-bis（dimethylsilyl）anthracene were synthesized. The reactions of these compounds with 4,4r-bis（phenylethynyl） biphenyl using RbCI（PPh3 ）3/NaI as catalyst through hydrosilylation resulted in corresponding unsaturated polycarbosilane. Further studies on the photophysical properties of polymers show that polymers present a fluorescence enhancement signal. Taking p-nitroaniline as quenchers, the fluorescence quenching efficiency of the polymers still keeps good quenching effect at extremely low concentration（10-6 mol/L）. |
