An exceptionally stable core–shell MOF/COF bifunctional catalyst for a highly efficient cascade deacetalization–Knoevenagel condensation reaction

Abstract

A novel strategy has been developed to construct a highly stable core–shell MOF@COF (PCN-222-Co@TpPa-1) bifunctional catalyst through strong π–π stacking interaction. This hybrid material with spatially isolated antagonistic acid–base sites can effectively catalyze the deacetalization–Knoevenagel condensation cascade reaction.
