In recent years, materials with circularly polarized luminescence (CPL) properties have attracted increasing attention from both academia and industry due to their promising applications in 3D displays, anti-counterfeiting encryption, optical data storage, bioimaging, and spintronic devices. Among these materials, macromolecular co-assembly system has emerged as one of the most appealing candidates, offering advantages such as improved processability and enhanced luminescence dissymmetry factors. In this review, we systematically summarize recent representative advances in macromolecular co-assembly systems with CPL properties, categorizing them into three main types: (1) co-assembly systems comprising a macromolecule dye, (2) co-assembly systems comprising a macromolecule chiral inducer, and (3) co-assembly systems comprising both a macromolecule chiral inducer and macromolecule dye. These systems encompass a wide range of macromolecular structures, including both biomacromolecules and synthetic polymers. Furthermore, we discuss the existing challenges in macromolecular CPL co-assemblies and provide an outlook on future research directions. We believe this review will enable researchers across multiple disciplines to quickly grasp the current status of macromolecular CPL co-assembly systems and inspire further exploration and innovation in this rapidly evolving field.
