为获得高效的发光液晶材料
将席夫碱结构单元引入-氰基二苯乙烯体系
合成了(Z)-2-(4-((E)-4-丁氧基-2-羟基苯乙烯氨基)苯基)-3-(4-丁氧基苯基)丙烯腈(BHPA)。通过紫外-可见吸收光谱和荧光光谱
研究其聚集诱导发光增强(AIEE)性质;利用热重分析(TGA)、差示量热扫描(DSC)、偏光显微镜(POM)研究其热力学性质和液晶性质。结果表明
BHPA是具有AIEE特性的发光液晶材料
取向的BHPA膜具有发光各向异性
其线偏振度约为0.41。
To obtain efficient luminescent liquid crystals materials
(Z)-2-(4-((E)-4-butoxy-2-hydroxybenzylideneamino)phenyl)-3-(4-butoxyphenyl)-acrylonitrile (BHPA) was designed and synthesized
by introducing the Schiff base unit into -cyanostilbenzene system. The aggregation-induced emission enhancement (AIEE) was studied by UV-Vis absorption spectra and photoluminescence (PL) spectra. Thermodynamic properties and liquid crystals (LCs) properties of BHPA were investigated with TGA
DSC and POM. The results show that BHPA is a luminescent liquid crystals material with AIEE
and the ordered orientated film of BHPA possesses luminescent anisotropic property with the linear polarization of 0.41.
