摘要:通过苯乙炔基锂和氯硅烷的偶合反应合成了系列含苯乙炔基共轭单体(PES)。通过红外光谱(FT-IR)、核磁共振(1H-NMR、13C-NMR、29Si-NMR)、质谱分析(MS)和元素分析(EA)对其结构进行了表征,利用紫外光可见分光光谱(UV-Vis)和光致发光光谱(PL)研究了共轭单体的荧光性能,讨论了不同共轭结构与单体性能之间的依赖关系。结果表明,合成得到的共轭单体易溶于常见的有机溶剂(四氢呋喃、氯仿、丙酮、甲苯等)。而且随着单体结构中共轭程度的增大,紫外吸收光谱的最大吸收峰和荧光光谱的发射峰均发生不同程度的红移。其中,四苯乙炔基硅烷(TPES)由于结构极具对称性且共轭程度最高,发射峰红移至368 nm和738 nm处,在可见光范围内发射红光。
Series of conjugated monomers(PES) were synthesized by pnenyletnyny~ .u,~ 29 ~ through coupling reaction. The structures were confirmed by FT-IR, 1H-NMR, 13C-NMR' S^-NMR, mass spectrometry(MS) and elemental analysis(EA). The fluorescence properties of conjugated monomers were studied by UV-Vis and photoluminescence(PL). The relationship between different conjugated structures and properties of monomers was discussed. The result show that the obtMned conjugated monomers can be dissolved in common ordinary solvents(THF, chloroform, acetone, toluene, etc). As the conjugated degree of monomer structure increasing, the red shift of the maximum absorption peak of UV absorption and fluorescence emission peak occurs in different degree. Anlong all the obtained conjugated monomers, the structure of tetra(phenylethynyl) silane(TPE$) has a great symmetry and the highest conjugation extent, its emission peaks red shift to 368nm and 738nm, and emits red light in the visible rmlge.
