摘要
Covalent organic frameworks (COFs) and their applications in photocatalysis have been extensively studied, but the instability of imine‐linked COFs is an important factor limiting their performance. In this work, two imine‐linked COFs were successfully converted to amide‐linked COFs through post synthetic modification (PSM). The oxidized COFs presented lower binding energy to O2, exhibited higher photocatalytic activity for oxidation of thioethers and coupling of benzylamines with excellent stability. The present work can serve as a reliable reference for the development of novel highly active and stable COF‐based photocatalysts.
