以二苯乙炔和不同取代基的硅烷为原料,通过1,1-位取代反应,合成噻咯衍生物,并对合成工艺条件进行优化.结果表明,原料摩尔比为1∶0.5和改变加料顺序,产物产率有较大提高,能达70％.硅烷取代基官能团越大,产物越易合成,产率越高,能达75％以上.对合成产物用氢核磁共振、红外光谱进行了表征,并通过紫外光谱和荧光光谱研究了其发光性能.%A new silole derivatives were synthesized from diphenylacethlene and silane with different sub-stitutional group by 1,1 -substituted and the synthetic process was optimized. The results showed that the product yield was higher up to 70% when the molar ratios of material was 1-0,5 and the charging order of materials was changed. When the Si-substitutional group was bigger, the product was easily synthesized and the product yield was higher up to 75%. The products were characterized by IR and H NMR, The light-emitting properties were studied by UV-Vis spectroscopy and fluorescence spectrometry.
