Tunable circularly polarized luminescence from molecular assemblies of chiral AIEgens

A tunable CPL response is achieved through regulating the aggregated structures of AIEgens in solution and solid states. Interestingly, DPCE-ECh exhibits a smectic C* phase with a high dissymmetry factor ( <italic>g</italic> _CD = −0.20 and <italic>g</italic> _lum = +0.38).
