Strong CPL-active liquid crystal materials induced by intermolecular hydrogen-bonding interaction and a chirality induction mechanism

A novel co-assembly material can emit strong CPL signals (λem = 485 nm, glum = +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.
