Construction of binary donor–acceptor conjugated copolymer in g-C3N4 for enhanced visible light-induced hydrogen evolution

Grafting π-conjugated donor units into graphitic carbon nitride (g-C3N4) represents a promising alterative to improve its light absorption range and charge transfer kinetics. To this end, we here report an efficient intramolecular g-C3N4-based conjugated copolymers via the one-spot thermal copolymerization for not only reduces the bandgap to 2.56 eV and thus expand the visible-light harvesting capability, but also accelerates the separation...
