A series of 12-connected lanthanide cluster based metal-organic frameworks (MOFs) have been constructed by [Ln(μ-OH)(COO-)] secondary building units (SBUs) and 2-aminobenzenedicarboxylate (BDC-NH) ligands. These obtained materials exhibit high chemical stability and generic thermal stability, especially in acidic and basic conditions. They also present commendable CO adsorption capacity, and Yb-BDC-NH was further confirmed by a breakthrough experiment under both dry and wet conditions. Moreover, these materials possess both Lewis acid and Brønsted base sites that can catalyze one-pot tandem deacetalization-Knoevenagel condensation reactions.
通过[Ln(μ-OH)(COO-)]二级构筑单元（SBUs）和2-氨基苯二甲酸酯（BDC-NH）配体构建了一系列基于12连接镧系元素簇的金属有机框架（MOF）。这些所得材料表现出高化学稳定性和一般的热稳定性，尤其是在酸性和碱性条件下。它们还具有值得称赞的CO吸附能力，并且通过在干燥和潮湿条件下的突破实验进一步证实了Yb-BDC-NH。此外，这些材料同时具有路易斯酸和布朗斯特碱位点，可催化一锅串联脱缩醛-Knoevenagel缩合反应。
