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 (vertical bar g(lum)vertical bar) value of 4.3 x 10(-3) and a high quantum yield Phi(F, 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 (C) 2020 Chinese Chemical Society and Institute of Materia Medica, Chinese Academy of Medical Sciences.
