“…The authors expect that CPL can be more precisely controlled using solid-phase peptide synthesis to obtain peptides with well-defined structures. Some research groups that conducted studies on the peptide-based regulation of CPLs recently reported that they succeeded in generating CPL from achiral molecules incorporated into peptide assemblies and peptide-based assemblies [7][8][9][10][11][12][13][14][15]. These research groups used peptides of various sizes, from dipeptides to polymeric peptides, to form peptide aggregates.…”

Light that rotates in a circular spiral when viewed from the front is known as circularly polarized luminescence (CPL), and can be divided into two types, namely, left- and right-rotating light. To emit both left- and right-rotating CPLs, two types of optically active luminophores, namely, enantiomer D- and L-bodies, are generally required. This mini-review mainly discusses our latest study on CPL properties via the control of the pyrene ring as the luminescent unit incorporated into chiral peptides. In this study, optically active peptide–pyrene organoluminescent materials that emit CPL were synthesized by combining a peptide as a frame and two pyrene rings as a luminescent unit. By adjusting the interpyrene distance, external conditions, and absolute chiral configuration (D- or L-configuration), the chiral spatial configuration of the luminescent pyrene ring was precisely controlled. Consequently, the direction of CPL rotation from pyrenylalanine-containing peptides with the same configuration was successfully controlled.

Materials with circularly polarized luminescence (CPL) exhibit great application potential in biological scenes such as cell imaging, optical probes, etc. However, most developed materials are non‐aqueous and toxic, which seriously restricts their compatibility with the life systems. Thus, it is necessary to explore a water‐based CPL system with high biocompatibility so that to promote the biologic application process. Herein, a facile and efficient route to achieve the CPL properties of a functional aqueous solution is demonstrated by the combination of 0D quantum dots (QDs) and 2D chiral nanosheets. Benefited by the specific absorption ability of nanosheets for left/right‐handed CPL, the QDs adsorbed onto the surface of nanosheets through hydrogen bond interactions showed apparent CPL features. In addition, this system has a good extensibility as the CPL property can be effectively regulated by changing the kind of emissive QDs. More importantly, this water‐based nano‐composite with facile fabrication process (one‐step mixing) is suitable for the real applications, which is undoubtedly beneficial for the further progress of functional CPL materials.
