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'-(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
