Ternary polymer dispersed cholesteric liquid crystals (PD-CLCs) prepared by doping AIE-active binaphthyl-based molecules (R/S-AD, chiral dopant) and the achiral liquid crystal fluorescent polymer, poly(p-phenylene ethynylene) (LC-PPE, CPL emitter) into 5CB, can emit strong circularly polarized luminescence (CPL) with gem up to 0.97. This work develops a new strategy for designing strong CPL materials.
