School of Materials Science and Engineering, Tianjin Key Lab for Rare Earth Materials and Applications, Smart Sensing Interdisciplinary Science Center, Renewable Energy Conversion and Storage Center (RECAST), National Institute for Advanced Materials, Nankai University, Tianjin, 300350, China.

The nonlinear chiroptical properties of chiral metal halide perovskite has attracted substantial attention in recent years. In order to overcome the inherent limitations of metal halide, such as high costs, potential toxicity, challenges with recycling, especially the limited laser-induced damage threshold (LDT), we have successfully constructed the first chiral metal-free anti-perovskite, with the aim of utilizing it in second harmonic generation-circular dichroism (SHG-CD). Moreover, the anti-perovskite composed entirely of small organic ions typically display a more extensive transparent window, which could contribute a high LDT.
