The fine-tuning of metal-based molecular building blocks in Zn-MOF-74 through post-synthetic cation exchange with Ca2+ significantly enhances its basicity and corresponding catalytic performance. The resulting material, exemplified by Ca/Zn-MOF-74, is shown through Knoevenagel condensation to give an improved product yield over the parent Zn-MOF-74 and Ni/Zn-MOF-74.
通过后合成的阳离子交换用 Ca2+对基于金属的分子构建块在 Zn-MOF-74 中的微调，显著提高了其碱性和相应的催化性能。所得到的材料，以 Ca/Zn-MOF-74 为例，通过 Knoevenagel 缩合反应给出了比母体 Zn-MOF-74 和 Ni/Zn-MOF-74 更高的产物收率。
