fluorescence emission in CHCl3 solutions were observed as similar broad band in visible blue region (ca. 430 nm). The quantum yields (Φ) were ranged from 0.19 to 0.37. The optical properties support the σ–π conjugation of the silylene and aromatic heterocycle groups, and the substituents on silicon atoms have negligible effect on the photoproperties.
聚[亚甲硅烷基-(1,2,3-三唑-4-基)-1,4-亚苯基]是由二乙炔基硅烷和1,4-经由铜(I)催化的叠氮化物和炔烃环加成(CuAAC)聚合制备的二叠氮苯。有机硅单元有助于π-共轭单元之间的电子跃迁,以及改善聚合物的溶解性和可加工性。傅里叶变换红外光谱(FT-IR)和核磁共振光谱(NMR)已用于确认这些聚合物的结构。聚合物的紫外-可见光谱在270 nm附近表现出几乎相同的吸收,在CHCl 3溶液中的荧光发射在可见的蓝色区域(约430 nm)观察到类似的宽带。量子产率(Φ)的范围从0.19到0.37。光学性质支持亚甲硅烷基和芳族杂环基团的σ - π共轭,并且硅原子上的取代基对光性质的影响可忽略不计。
