Chiral 3D Perovskite Formation Induced by Chiral Templates.

Chiral 3D perovskites pose challenges compared to lower-dimensional variants due to limited chiral organic cation options. Here, we present a universal and controlled method for synthesizing chiral 3D lead halide perovskites using organic amines or alcohols as chiral templates. Introducing these templates to PbCl in ,-dimethylformamide (DMF) under acidic conditions induces the crystallization of R/S [DMA]PbCl (DMA = dimethylamine).
