•A new optical switch based on AIE-active luminescent liquid crystals was developed.•The mixture material can emit partially linearly polarized light.•It is possibly to modulate photoluminescence intensity and its polarization.•It has the potential to be used in improved optical devices.
We found reversible photo/thermal isomerization of the α-cyanostilbenic derivative (Z)-2-(4-aminophenyl)-3-(4-(dodecyloxy)phenyl)-acrylonitrile, (Z)-CN-APHP, which is accompanied by a large decrease in compatibility when mixed with a nematic liquid crystal. Moreover, a novel optical switch using a CN-APHP doped liquid crystal that emits partially linearly polarized light is investigated. By controlling the trans–cis isomerization of CN-APHP, it is possibly to modulate not only photoluminescence intensity but also its polarization. This could open possibilities to design improved optical devices.
