摘　　要：A new chiral bromobinaphthol-pyrene compound was developed to achieve a green circularly polarized luminescence(CPL)from its excimer with a dissymmetry factor(|glum|)value of 4.3×10^-3 and a high quantum yieldΦF,solid up to 55.9%,while no CPL signals could be observed for the blue luminescence from unimolecule.Meanwhile,reversal CPL signals can be observed from both concentrated solution and solid.
