Introduction of electron-deficient unit in resorcinol-formaldehyde resin to construct donor–acceptor conjugated polymer for enhancing photocatalytic H2O2 production

Intramolecular donor–acceptor conjugated polymer was constructed in resorcinol-formaldehyde resin by embedding benzothiadiazole, which can reduce the Gibbs free energy for two-electron oxygen reduction and improve photocatalytic H 2 O 2 evolution.
