Electrostatic Field Effects in Covalent Organic Frameworks for Photocatalytic CO 2 ‐to‐CO Conversion beyond 1000 mmol g Co −1 h −1

and a quantum efficiency of 5.67% at 420 nm, which is 17 times that of the pristine COF. This strategy offers a novel approach to designing various photocatalytic systems aimed at efficient chemical transformations.
