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.
通过强π-π堆积相互作用，已开发出一种构建高度稳定的核壳型金属有机框架@共价有机框架（PCN-222-Co@TpPa-1）双功能催化剂的新策略。这种具有空间隔离的拮抗酸碱位点的杂化材料能够有效催化缩醛脱除-Knoevenagel缩合级联反应。
