Circularly polarized luminescence from supramolecular assemblies based on small molecules

This is the authors' abstract. We don't add key points for this paper.

Circularly polarized luminescence (CPL)‐active materials have a wide range of technological applications. Traditionally, creating CPL‐active materials relies on the use of chiral luminophores. In contrast, supramolecular assembly introduces an innovative and promising strategy for developing CPL‐active materials not only from chiral luminophores but also from achiral species. This approach significantly enriches the diversity of CPL‐active materials. It also offers an effective means to optimize the performance of CPL‐active materials, such as enhancing the asymmetry factor | g lum |. Compared to polymers, the assembly of small molecules is generally easier to control. This review systematically summarizes the recent progress and developments in CPL from small‐molecule assemblies, particularly focusing on differences, merits, and demerits of three typical assembly modes. The aim is to provide valuable insights for the future development of chiroptical materials.
