Directing robust built-in electric fields via imine linkage orientation in COFs for efficient dehydrogenative organic transformation coupled with H 2 O 2 photosynthesis

The isomeric imine linkage in D–A COFs boosts the built-in electric field for enhanced charge separation and an ∼30% reduction in exciton binding energy, leading to high-performance organic dehydrogenation coupled with H 2 O 2 production.
