Structurally coloured polymer films with circularly polarized luminescence (CPL) properties were prepared by the  photopolymerization of cholesteric liquid crystal mixtures doped with aggregation-induced emission (AIE)-active tetraphenylethylene. The films show good CPL performance with the luminescence dissymmetry factor up to 0.58 and enhanced fluorescence efficiency.
