Chiral self-assembly of block copolymers with rigid conjugated polymer backbones can create a variety of nanostructures, including micelles and helical nanofibers with chiroptical properties. Chiral perovskite quantum dots (PQDs) with high quantum efficiency have also attracted interest use for chiral sensing, optical encryption, and biological probes. Previous chiral perovskites capped by chiral ligands have limitations in inducing circularly polarized luminescence due to the reduction of quantum yield after ligand exchange and purification process. We study chiral polymer/perovskite hybrid systems inducing chiral regular arrangement of PQDs along crystallization-driven self-assembled polymer nanowires in the solution state for CPL enhancement. Specifically, we report chirality amplification mechanisms by co-assembly between the chiral building block and PQDs. This work would provide a new hybrid system to enhance chirality parameters and circularly polarized luminescence property.
