Circularly polarized luminescence and nonlinear optical harmonic generation based on chiral zinc halides

Chiral hybrid metal halides have grabbed extensive attention in linear and nonlinear chiroptics. Herein, 0D chiral zinc halides, ( R -/ S -2-MP)ZnCl 4 , have been fabricated, which demonstrate high efficiency second-order nonlinear optical responses. Incorporating Sb 3+ into the chiral zinc halide matrix triggers the circularly polarized luminescence effectively with a balance between quantum yield and luminescence dissymmetry factor. The transfer of chirality from organics breaks inherent symmetry, leading to clear second-order NLO responses for chiral zinc halides. Additionally, successful CPL can be induced by doping chiral zinc halides with Sb 3+ containing 5s 2 electrons.
