Biomolecule‐Based Circularly Polarized Luminescent Materials: Construction, Progress, and Applications

Chiral materials related to circularly polarized luminescence (CPL) make up a rapidly developing new field that has broad application prospects in optoelectronic devices, selective recognition, biomedicine, and other fields. Biofunctional chiral materials are also attracting increasing attention because of their unique biocompatibility, chiral recognition, and coding. However, there has been little discussion on biomolecule‐based CPL till now. In this Review, the latest progress in CPL materials related with biomolecules are reviewed, including the chiral construction from molecular level to giant microstructure, as well as their emerging applications. In addition, we discuss the challenges and prospects of bio‐based CPL materials, hoping this work will provide new perspectives and insights for more related research. In this Review, the generation, induction and amplification of CPL‐active materials based on biomolecules, as well as their emerging applications due to sensitive CPL signals, are reviewed and prospects for future development considered. New insights are also provided towards the design of chiral functional biomaterials and their potential applications.
