A family of heterometallic metal-organic frameworks (MOFs) (CPM200s) harmoniously coexisting as Lewis acids and base (azo) sites were prepared. Seven CPM200s were employed as multifunctional heterogeneous cascade catalysts for the one-pot deacetalization-Knoevenagel reaction in a solvent-free system. Benefiting from the cooperation between Lewis acids from the open metal sites and base sites from the ligands, the CPM200s showed high activity and selectivity for the tandem reaction. The heterometallic 3D porous framework reported here not only offers a combination of two opposite active sites in the same framework of materials but also increases mass transfer of the substrate, thus maximizing the efficiency and substrate selectivity of the bifunctional catalysts. The CPM200s showed the highest turnover frequency (TOF), outperforming that of the reported MOFs in tandem with the deacetalization-Knoevenagel reaction. A strong correlation between the TOF and charge-to-radius ratio (z/r) of metal ions in the CPM200s was observed for the first time. The bifunctional CPM200s catalysts can be reused five times without significant loss of activity.

We demonstrate the one-pot synthesis of highly porous crystalline metal−organic frameworks, [Zn<sub>4</sub>O(piperazine dicarbamate)<sub>3</sub>], an analogue of [Zn<sub>4</sub>O(1,4-benzenedicarboxylate)<sub>3</sub>] (MOF-5), directly from atmospheric pressure CO<sub>2</sub> gas and piperazine derivatives at 25 °C. The structures showed high CO<sub>2</sub> contents over 30 wt% and surface areas of 1270−2366 m<sup>2</sup> g<sup>−1</sup>. We also show that the synthesis is feasible even by the use of 400 ppm of CO<sub>2</sub>.
