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。
