Nitrogen‐Site Isomerism Unlocks Exciton Dissociation in Vinylene‐Linked COF‐Based Photocatalysts

EcoEnergy, EarlyView.
Two regioisomeric vinylene‐linked covalent organic frameworks (COFs) constructed from diazine units with different nitrogen positions are developed for photocatalytic hydrogen evolution reaction (HER). Although structurally similar, the isomeric COFs exhibit distinct electron distribution and charge‐separation behaviors, leading to a more than twofold ...
