Molecular Dual-Functionalization Unlocks Room-Temperature Phosphorescence of Graphitic Carbon Nitride for Environmentally Robust Encryption

Abstract

We report a naphthyl-phenyl dual-functionalized graphitic carbon nitride (g-CN) with robust room temperature phosphorescence (RTP). Its synergistic molecular design promotes triplet exciton generation and radiative recombination, delivers excellent temperature and solvent resistance, and exhibits great application potential for advanced information encryption in diverse harsh and complex environments.
