Regulation of Circularly Polarized Luminescence in Multicomponent Supramolecular Coassemblies

Abstract Circularly polarized luminescence (CPL) active materials have received increasing attention due to their promising applications in fields such as photoelectric devices, spintronic devices and information storage systems. In developing CPL‐active materials, the key issue is to amplify the dissymmetry g‐factor (g lum ) and flexibly regulate the handedness, luminescence color and other properties. Relying on non‐covalent forces, multicomponent assembly provides an effective solution for control over CPL features. This Minireview summarizes recent progress in the regulation and amplification of CPL‐active materials in multicomponent coassembled systems, where the role of solvents, metal ions, quantum dots, achiral luminophores and nematic liquid crystals as well as a series of photophysical approaches including Förster resonance energy transfer (FRET), charge transfer (CT), arene‐perfluoroarene (AP) interactions and photon upconversion between different components are discussed. Furthermore, future challenges and opportunities of CPL‐active materials in multicomponent assembly systems are also reviewed. This Minireview aims to provide inspiration for the rational design and manufacture of CPL‐active materials based on multicomponent assembly.
