Dual-responding circularly polarized luminescence based on mechanically and thermally induced assemblies of cyano-distyrylbenzene hydrogen bonding liquid crystals

Abstract

Circularly polarized luminescence controlled by both mechanics and temperature was observed for the first time. The cyano-distyrylbenzene-cholesterol liquid crystals exhibited not only mechanochromism and thermochromism but also mechanically induced and thermally induced circularly polarized.
