Tetra-Armed Oligo(Phenylenevinylene)-Based Covalent Organic Frameworks for Enhanced Photocatalytic Hydrogen Evolution

Abstract

We report tetra-armed OPV-based imine COFs prepared by controlled-growth synthesis and show that imine linkage orientation dictates charge transport and hydrogen evolution. Under visible light, COF-924 reaches 154.8 mmol g-¹ h-¹, 268 times its isomer, establishing linkage isomerism as a powerful design principle for COF photocatalysts.
