Mixed-Linker Strategy in Covalent Organic Frameworks for Enhanced Sunlight-Driven Photocatalytic Oxidation Activity and Stability

Abstract

We present a simple mixed-linker strategy to enhance the photocatalytic oxidation activity and stability of covalent organic frameworks semiconductors. The TpTfbPa-COF, featuring an unconventional reversed AA-stacking structure with both imine and ketoamine linkages, exhibits excellent structural stability and superior photocatalytic performance compared to the fully imine-linked TfbPa-COF and the fully ketoamine-linked TpPa-COF.
