设计合成了一种a-氰基取代二苯乙烯衍生物(Z)-2-(4-氨基苯基)-3-(4-辛烷烷氧基苯基)丙烯腈( CN-APHP)。通过紫外吸收光谱、荧光发射光谱研究了CN-APHP的光物理性质。利用差示扫描量热分析和偏光显微镜研究了化合物的液晶性质。结果表明,CN-APHP在59~85℃之间形成近晶相液晶,是一种具有聚集态诱导发光增强特性的液晶材料。有序取向的CN-APHP薄膜具有发光各向异性,其线偏振度约为0.3。“,”Liquid-crystal molecule ( ( Z)-2-(4-aminophenyl)-3-(4-( dodecyloxy) phenyl)-acryloni-trile, CN-APHP) with strong fluorescence in the aggregation state was designed and synthesized. Ultraviolet absorption spectrum, fluorescence emission spectrum were used to study the photo physi-cal property of the CN-APHP. Differential scanning calorimetry ( DSC) and polarizing optical micro-scope ( POM) were used to study the liquid crystal property of compound CN-APHP. The results in-dicate that a smectic liquid crystal is observed from 59 to 85 ℃. The ordered orientated film of CN-APHP shows obvious luminous anisotropy and the linear polarization is 0 . 3 .
