Enhancing phosphorescence by coassembling organic molecules with laponite and Poly(vinyl alcohol) Dyes Pigments (IF 4.5) Pub Date : 2024-02-16 Shuang Zou, Guihua Bao, Xiao Liu, Qingyu Niu, Congmin Sun, Zhiqiang Li, Jian Wang
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
