Abstract
In this paper we designed a kind of aggregation-induced emission (AIE) chiral fluorescence emitters (R/S-BINOL-CN enantiomers) in the aggregate state. Chiral emissive nematic liquid crystals (N*-LCs) prepared by doping this kind of AIE-active R/S-BINOL-CN enantiomers into a common achiral nematic liquid crystal (N-LC, E7) can self-assemble as the regularly planar Grandjean texture leading to high luminescence dissymmetry factor (glum ) of aggregation-induced circularly polarized luminescence (AI-CPL) signal up to 0.41, which can be attributed to dipolar interactions from polar cyano groups and π-π interactions between binaphthyl moiety of the dopant R/S-BINOL-CN and biphenyl group of the host molecules (E7).
