研究了在空气中经紫外光辐照前后的聚（甲基环己基硅烷）（简记为：PMCS）溶液和甲基环己基硅烷甲基苯乙基硅烷共聚物（简记为：Copolymer）溶液的荧光光谱.结果表明，随着紫外光光照时间的增加，这两种聚硅烷溶液的荧光光谱峰位依次蓝移，荧光强度依次降低.并用UV光谱，GPC，XPS及IR光谱研究了在空气中经紫外光辐照前后的PMCS和Copolymer溶液.结果表明，这两种聚硅烷溶液的荧光光谱峰位蓝移及荧光强度降低，与聚硅烷发生了光降解和光氧化过程有关.
The solution of poly (methylcyclohexylsilane) (abbreviated as PMCS) and methylcyclohexylsilylmethylphenethylsilane copolymer (abbreviated as: Copolymer) in air before and after irradiation with ultraviolet light The fluorescence spectra of these two polysilane solutions were blue-shifted and the fluorescence intensity decreased in turn with the increase of ultraviolet light irradiation time.The results of UV, GPC, In the PMCS and Copolymer solution before and after UV irradiation.The results show that the blue fluorescence peak position and the fluorescence intensity of the two polysilane solutions decrease, which is related to the photodegradation and photooxidation of the polysilane.
