Abstract

Abstract The insufficient exciton ( e − ‐ h + pair) separation/transfer and sluggish two‐electron water oxidation are two main factors limiting the H 2 O 2 photosynthetic efficiency of covalent organic frameworks (COFs) photocatalysts. Herein, we present an alternative strategy to simultaneously facilitate exciton separation/transfer and reduce the energy barrier of two‐electron water oxidation in COFs via a dicyano functionalization. The in situ characterization and theoretical calculations reveal that the dicyano functionalization improves the amount of charge transfer channels between donor and acceptor units from two in COF‐0CN without cyano functionalization to three in COF‐1CN with mono‐cyano…
