Abstract

Abstract 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.
