Abstract

N-Oxidation of imine linkages and pyridine moieties in pyridine-based covalent organic frameworks induces dual-site polarization. Due to the optimized polarization density and plentiful N⁺–O⁻ polar units, TFPyB-O-COF exhibits an exceptional NH₃ production rate of 519.8 µmol g⁻¹ h⁻¹ for photocatalytic N₂ reduction, which is proposed to proceed via an alternating association mechanism.
