The　development　of　photocatalytic　systems　that　enable　the　simultaneous　production　of　H2O2　and　value-added　organic　chemicals　presents　a　dual　advantage:　generating　valuable　products　while　maximizing　the　utilization　of　solar　energy.　Despite　the　potential,　there　are　relatively　few　reports　on　photocatalysts　capable　of　such　dual　functions.　In　this　study,　we　synthesized　a　series　of　donor-acceptor　covalent　organic　frameworks　(COFs),　designated　as　JUC-675　to　JUC-677,　to　explore　their　photocatalytic　efficiency　in　the　co-production　of　H2O2　and　N-benzylbenzaldimine　(BBAD).　Among　them,　JUC-675　exhibited　exceptional　performance,　achieving　a　H2O2　production　rate　of　22.8　mmol　g(-1)　h(-1)　with　an　apparent　quantum　yield　of　15.7　%,　and　its　solar-to-chemical　conversion　efficiency　was　calculated　to　be　1.09　%,　marking　it　as　the　most　effective　COF-based　photocatalyst　reported　to　date.　Additionally,　JUC-675　demonstrated　a　high　selectivity　(99.9　%)　and　yield　(96　%)　for　BBAD　in　the　oxidative　coupling　of　benzylamine.　The　underlying　reaction　mechanism　was　thoroughly　investigated　through　validation　experiments　and　density　functional　theory　(DFT)　calculations.　This　work　represents　a　significant　advancement　in　the　design　of　COF-based　photocatalysts　and　the　development　of　efficient　dual-function　photocatalytic　platforms,　offering　new　insights　and　methodologies　for　enhanced　solar　energy　utilization　and　the　synthesis　of　value-added　products.
