摘要
用格氏法合成了 (α 萘基 )甲基二氯硅烷 ,并以其与二苯基二氯硅烷为原料 ,采用钠缩合法合成了 (α 萘基 )甲基硅烷与聚二苯基硅烷的共聚物。IR ,UV ,用X 射线和偏光显微镜对它的结构进行了分析 ,用热重分析法测试它的热稳定性 ,并用紫外和荧光光谱对它的光学性能进行了表征。结果表明 ,这种聚合物具有良好的热稳定性 ,它在紫外区产生较强的紫外吸收和荧光发射 ,可望成为一种良好的光学材料。
The methyl (naphthyl) dicholosilane was synthesized,and the copolymer of naphthyl methylsilane and polydiphenylsilane was prepared.Its Structure and thermal stability were studied by infrared spectra,X-ray diffraction,polarization microscope and thermogravimetry.Fluorescence spectra and ultraviolet spectra of polymer in cyclohexane were studied.These results indicate that thermalstability and optical character of copolymer are favorable and it will be a kind of optical materical.
