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 investi-gated. 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 dis-play technology with a simple device design and substantially increase the device brightness, con-trast, efficiency, when the luminescent liquid crystal material is used in LCD.
