ABSTRACT

Chiral assembly endows perovskite materials with well-defined structural chirality and optical anisotropy, creating unique opportunities for multidimensional modulation in optoelectronic applications. Recent advances have demonstrated effective amplification of chiral signals, band structure engineering, and enhanced spin-orbit coupling through diverse strategies, including template-guided assembly, ligand-induced assembly, and several emerging approaches. This review highlights the latest progress in chiral perovskites for circularly polarized light-emitting devices, polarization-sensitive photodetectors, polarization imaging, optical communication and encryption, and spintronic and quantum information applications.
