Rationalizing the design and implementation of chiral hybrid perovskites

Molecular asymmetry occurs at all scales in nature, spanning organic to inorganic frameworks with consequences of high significance. For this reason, asymmetric organic and inorganic materials are incessantly gaining considerable interest owing to the opportunity of reaching tunable chiral signatures. In recent years, the chiral hybrid organic-inorganic perovskites in which the chiral organic ligands usually induce the symmetry breaking are receiving growing attention. Their circularly polarized emissions without the need for expensive ferromagnets or extremely low temperatures are appealing features for the industry. Until now, there has been no clear relationship between the structure of the chiral perovskites and the generated signal. This review aims at focusing on the supramolecular chiral amplification mechanisms in asymmetric perovskites, rationalizing how to enhance their chiral emission signatures. We conclude by broadening our view toward future challenges in exploring modern simulation protocols to optimize the design of chiral hybrid perovskites.
