Unconventional aggregation-induced emission property with clusteroluminescence mechanism from natural compounds and applications

Since the issue of environmental pollution has become urgent concerns due to the energy crisis and global warming caused by the massive consumption of fossil resources, researchers around the world are exploring new renewable resources to achieve sustainable development of future society. Thus, some materials from natural products with aggregation-induced emission (AIE) behavior with clusteroluminescence (CL) mechanism and the room temperature phosphorescence phenomenon (RTP) were urgent needed. In terms of their excellent biocompatibility, natural availability, and green chemistry characteristic demonstrated a much more significant approach to abundantly obtain high-performance of new functional materials without resulting in huge energy costs and environmental burden. However, since there are little reports on CL mechanism with the RTP performance and related applications from natural resources, this review introduces new types from natural sources that can be used to discovering more luminescent materials and their potential applications. This review also reported the recent progress of new AIE materials found from nature and the applications. Moreover, it also provides more inspiration for the structure design and development based on AIE biomaterials related applications inspired in the future.
