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

Abstract

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 × 10⁻³ for R/S-P1.
