Post-synthetic ligand exchange (PSE) approach has been widely used for the incorporation of functional moieties into metal–organic frameworks (MOFs) to achieve desired properties. It allows the replication of MOF superstructures with desired linker functionality through the conversion of preformed superstructures. However, this replication might turn to be unsuccessful if the conversion is a dissolution–recrystallization process. In this work, we report the inter-conversion of a variety of zeolitic imidazolate frameworks (ZIFs) following the PSE procedure using dimethylformamide as the solvent instead of alcoholic solvents. A dissolution–recrystallization process is demonstrated by the studies on the conversion of ZIF thin films and metal nanoparticle loaded ZIFs.

沸石咪唑酸酯骨架之间的相互转化：溶解-重结晶过程

合成后配体交换（PSE）方法已广泛用于将功能性部分掺入金属有机骨架（MOF）中以实现所需的性能。它允许通过转换预制的上层结构来复制具有所需链接功能的MOF上层结构。但是，如果转化是溶解－重结晶过程，则该复制可能会失败。在这项工作中，我们报告了在使用二甲基甲酰胺作为溶剂而不是醇类溶剂的PSE程序之后，各种沸石咪唑酸酯骨架（ZIF）的相互转化。ZIF薄膜和负载金属纳米粒子的ZIF的转化研究证明了溶解-重结晶过程。
