Three-dimensional (3D) halide perovskites have attracted considerable research interest, yet the selection of A-site cations is restricted by the Goldschmidt tolerance factor. To accommodate cations beyond this acceptable range, novel 3D perovskite analog structures with edge- and face-sharing motifs have been developed. Until now, these structures have been limited to divalent cations due to significant electrostatic repulsion when incorporating two monovalent cations.

Article Synopsis
- Chiral hybrid metal halides (CHMHs) are gaining attention for their excellent optoelectronic properties and flexibility, making them promising for applications in chiroptoelectronics, spintronics, and ferroelectrics.
- Previous attempts to synthesize stable chiral 3D structures, specifically CHFClNHPbI, at room temperature had been unsuccessful, limiting the study of their properties.
- This study successfully created two types of chiral lead iodide hybrids and demonstrated their unique optical activity and bulk photovoltaic effects, showcasing their potential in developing advanced chiral electronic devices.
