Abstract
Abstract Covalent organic frameworks (COFs) as appealing platforms have received tremendous interest in the field of photocatalytic H 2 evolution owing to their well‐defined structures and tailor‐made function. However, excitonic effects resulting from Coulomb interactions between electron–hole pairs are key rate‐determining processes in photocatalytic hydrogen evolution, which are usually ignored. Thus, it is of profound significance and highly desired, but it is still a challenge, to explore new routes to modulate excitonic dissociation in COFs for boosting photocatalysis. To address this challenge, Ni‐intercalated fluorenone‐based COFs (Ni‐COF‐SCAU‐1) at the imine linkage, are proposed for the first time,…
