Abstract

A novel co-assembly material can emit strong CPL signals (<i>λ</i><sub>em</sub> = 485 nm, <i>g</i><sub>lum</sub> = +0.076/-0.064) from an achiral AIE-active β-cyanostilbene (CYS) liquid crystal dye through intermolecular hydrogen bond (HB) interaction and chirality induction after a rapid cooling quench treatment.
