| 摘 要： | 具有聚集诱导发光增强效应的发光液晶材料,能有效地解决一般发光材料聚集时荧光猝灭和液晶自组装之间的矛盾,在液晶显示等领域有极大的应用价值。本文报道了一种自发光液晶材料(2Z,2'Z)-2,2'-(1,4-亚苯基)二(3-(4-己氧基)苯基)丙烯腈(PHPA)。研究了PHPA的聚集态发光性质、溶剂化效应、热力学性质及发光各向异性。结果表明,PHPA同时具有聚集态诱导发光增强效应和液晶性,其有序取向的薄膜发出的光具有各向异性。该发光液晶材料应用于液晶显示将能简化器件结构、增加亮度、对比度和能效。

| Abstract: | The luminescent liquid crystals (LLCs) with aggregation-induced enhanced emission can solve the conflicts between fluorescence quenching caused by the aggregation and the requirement of aggregation or self-organization for LCs. A novel LLC, (2Z, 2'Z)-2, 2'-(1, 4-phenylene)bis(3-(4-hexyloxy)phenyl)acrylonitrile (PHPA) was designed and synthesized. The aggregation luminescent properties, solvation effect, thermodynamic properties and emitting anisotropy of PHPA were investigated. The results demonstrate that PHPA has aggregation-induced emission phenomenon and LC phases, and the aligned thin film can emit anisotropic luminescence. It can greatly improve the display technology with a simple device design and substantially increase the device brightness, contrast, efficiency, when the luminescent liquid crystal material is used in LCD. |
