Abstract

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.
