Construction of Full-Color and White Luminescent Materials by a Supramolecular Polymer Gel System with Clusteroluminescence

Full-color luminescent materials, especially white-light-emissive materials covering the entire visible spectrum, are gaining increasing attention owing to their wide applications. The incorporation of clusteroluminescence into full-color luminescent materials could avoid the aggregation-caused quenching problem of traditional fluorescent dyes. In addition, supramolecular chemistry provides an efficient method to prepare tunable full-color and white luminescent materials through dynamic non-covalent interactions, thereby eschewing tedious organic synthesis and enabling stimuli responsiveness. Herein, we report a full-color and white luminescent system constructed by a supramolecular polymer gel with clusteroluminescence based on pillararenes. This supramolecular polymer gel exhibited unique clusteroluminescence and can serve as a matrix material for different dye molecules to prepare full-color and white luminescent materials. Due to the dynamic properties of the supramolecular polymer gel, the obtained materials showed stimuli-responsive fluorescence emission. Further, this system was successfully utilized in the fields of full-color and white-light-emitting diodes, multicolor inks, and information encryption.
