Metal–organic frameworks (MOFs) have been widely studied as new materials, and many structural regulation strategies have been reported. We report a new defective-MOF design strategy that involves a continuous process of pore space partition, metal center exchange, and ligand removal. In the whole process, the single crystal of MOF is well maintained, which not only points out a rare and clear route for the structure transformation process but also provides an indirect synthesis method for defective materials, which cannot accurately control the vacancy position. It was interesting to find that the removal of the selected ligand endows the MOF with larger pores, higher stability and excellent performance in the selective adsorption and separation of C₂H₄/C₃H₆ mixtures and natural gas mixtures.

通过连续结构转变创造具有更大孔隙和更高稳定性的气体分离MOF

金属有机骨架（MOF）作为新材料已被广泛研究，并报道了许多结构调控策略。我们报告了一种新的有缺陷的 MOF 设计策略，该策略涉及孔隙空间分配、金属中心交换和配体去除的连续过程。整个过程中，MOF的单晶得到了很好的保持，不仅为结构转变过程指明了一条罕见而清晰的路线，而且为无法精确控制空位位置的缺陷材料提供了一种间接合成方法。有趣的是，去除选定的配体使MOF具有更大的孔道、更高的稳定性以及在C ₂ H ₄ /C ₃ H ₆混合物和天然气混合物的选择性吸附和分离方面的优异性能。
