Hierarchical Chiral Supramolecular Assemblies from Amphiphilic Star-like Block Copolymers for Full-Color Circularly Polarized Luminescence

Circularly polarized luminescence (CPL) materials have attracted significant attention for next-generation photonic technologies, including three-dimensional displays, optical communication, information encryption, and anti-counterfeiting. However, simultaneously achieving efficient, stable, and full-color CPL emission, particularly in the red spectral region, remains a longstanding challenge due to weak chiral transfer, structural instability, and fluorescence quenching. Here, we report a star block copolymer-enabled chiral supramolecular co-assembly strategy that enables highly efficient and stable full-color CPL across the entire visible spectrum. The star-shaped block copolymer serves as a robust supramolecular scaffold that promotes cooperative molecular assembly while effectively transferring and amplifying chirality to achiral luminophores. Through precise control of the co-assembly process, blue, green, and red emitters are incorporated into well-defined chiral nanostructures exhibiting strong CPL activity with excellent optical performance. Notably, the assembled structures maintain their morphology, chirality, and emission properties for more than 100 days under ambient conditions, demonstrating exceptional long-term stability compared with conventional supramolecular systems. The platform also provides broad compositional versatility, allowing diverse luminophores to be integrated without compromising chiroptical properties. This universal supramolecular design overcomes key limitations of existing CPL materials by simultaneously achieving efficient chiral induction, full-color emission, and outstanding structural robustness. Our strategy establishes a general framework for constructing durable chiroptical materials and opens new opportunities for advanced photonic devices, secure information technologies, and next-generation optoelectronic applications.
