ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.A donor–acceptor (D–A) engineering strategy is applied to construct β‐ketoenamine‐linked COFs for CO2 photoreduction in pure water without sacrificial agents or photosensitizers. The designed TP‐TAPB COF, featuring the strongest D–A interaction, achieves a complete CO production rate of 464.6 μmol g−1. Strengthened intramolecular D–A interactions favor
