Comprehensive Summary

Chiral perovskites provide an ideal platform for the construction of linear and nonlinear optical materials due to their diverse chemical variability, structural tunability, and intrinsic non-centrosymmetricity which have broad application prospects for next-generation optoelectronic devices. In this work, a pair of 1D chiral lead halide perovskites (R/S-4MeOPEA)PbCl3 (4MeOPEA = (4-methoxyphenyl)ethylamine) were synthesized, and characterized systematically. Crystal structure analysis revealed that the one-dimensional (1D) inorganic chain formed by face-shared lead chloride octahedra was separated by the chiral organic spacers. The distorted octahedra endows them with broadband bluish-white light emission centered covering the range 350—700 nm with a width of 104 nm. In addition, the highly anisotropic second-harmonic generation (SHG) with a near unity polarization ratio was observed. This work presents a fresh example of 1D chiral perovskite with exotic linear and nonlinear optical properties, which could provide a new footstone for further optoelectronic devices.
