摘要
Room-temperature phosphorescent materials are widely concerned due to their potential applications in information encryption, anticounterfeiting and display. Herein, a rational strategy is designed by coassembling the carbazole derivatives with Laponite and poly (vinyl alcohol) (PVA) to inhibit their molecular rotation and vibrations. Laponite suppresses the nonradiative decay by abundant hydrogen bonds crosslinking with phosphorescent molecules and PVA chains. The synthesized inorganic-organic hybrid films are well used in information encryption and anticounterfeiting. Thus, this work provides a novel strategy for enhancing phosphorescence emission by doping organic molecules and Laponite in polymeric systems.
