Amplification effect of circularly polarized luminescence induced from binaphthyl-based zinc(ii) chiral coordination polymers

Two novel binaphthyl-based dipyrrin zinc(ii) chiral coordination polymers (R/S-P1) can be synthesized by coordination reaction. R/S-P1 can exhibit stronger Cotton effects and circularly polarized luminescence (CPL) emission signals compared with the chiral complex monomers (R/S-M1). The luminescence dissymmetry factors (g(lum)) can reach as high as 9 x 10(-3) for R/S-P1.
