Abstract
We present a simple mixed-linker strategy to enhance the photocatalytic oxidation activity and stability of covalent organic framework 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.
