Luminescent liquid crystals (LLCs) have attracted significant interest for organic optoelectronic applications, especially for the generation of linear polarized light. Here, a novel LLC molecule, 2-(4-(nonanealkoxy)phenyl)-3-(4-formamidephenyl)-acrylonitrile (CN-NPFA), is reported, which shows strong fluorescence in the solid state due to the aggregation-induced enhanced emission (AIEE) effect. Moreover, a well-aligned liquid crystalline film using AIEE-active molecules, is obtained using an in-plane electric field with an alignment layer. It exhibits highly polarized luminescence (ρ = 0.74) with a high fluorescence quantum yield. The device is both cheap and easy to fabricate, and has the potential to be used in practical electro-optic applications.

发光液晶（LLC）在有机光电应用中引起了极大的兴趣，特别是对于线性偏振光的产生。在这里，报告了一种新型的LLC分子2-（4-（壬烷烷氧基）苯基）-3-（4-甲酰胺苯基）-丙烯腈（CN-NPFA），由于聚集诱导，在固态下显示出强荧光增强排放（AIEE）效果。另外，使用具有取向层的面内电场，可以得到使用了AIEE活性分子的取向良好的液晶膜。它具有高偏振发光（ρ  = 0.74）和高荧光量子产率。该装置既便宜又易于制造，并且有可能在实际的电光应用中使用。
