Exploring π-extended chiral ligands for the direct detection of circularly polarized light in 2D chiral perovskites

초록

Perovskites incorporating chiral organic ligands are promising for circularly polarized light (CPL) photodetectors. This study introduces biphenyl-based chiral amines, (R/S)-BPEAs, which enabled the successful synthesis of chiral perovskites with larger-sized ligands. These new materials demonstrated improved circular dichroism and enhanced CPL detection, expanding the possibilities for CPL photodetectors.
