Inversion of Circularly Polarized Luminescence in Chiral PIM Membranes via Co-assembly with Achiral Perovskite Quantum Dots

Abstract

A pair of chiral polymers of intrinsic microporosity, denoted as (+)/(-)-CCS-PIM, were synthesized with robust circularly polarized luminescence (CPL). Co-assembly of chiral CCS-PIMs with achiral CsPbBr₃ quantum dots achieves CPL handedness inversion without emission shift. This simple strategy expands tunability of hybrid chiroptical materials, offering new design principles for optoelectronic applications.
