The N-deficient porous g-C3N4 with broadband white light emission was constructed by supramolecular copolymerization design, which combined organic copolymers cyanuric acid and 2,4,6-triaminopyrimidine melamine upon the mixture gas environment of (95%)N2/(5%)H2. Herein, we achieved great breakthrough in narrowing band gap from 2.64 to 1.39 eV. Furthermore, contrast pristine g-C3N4, demonstrated that wavelengths can be tuned narrow blue range, where optimal coordinate position is (0.297, 0.345). prepared overcomes limitation adjusting range optical properties while using conventional makes it more promising for applications solid-state displays.
