Synthesis and Photoluminescence Property of Luminescent Liquid Crystal Material
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.
