Linker exchange is a widely applied, robust technique for elaboration of metal-organic frameworks (MOFs) post-synthesis. The observation of core-shell microstructures under certain conditions was hypothesized to arise from diffusion rates into the MOF that are slower than linker exchange. Here the relative contributions of these processes are manipulated through solvent choice in order to modulate shell thickness and exchange extent. The findings allow tailoring MOF microstructure to application.
连接体交换是一种广泛应用的、强大的技术，用于合成后金属有机框架（MOF）的精细制备。在某些条件下观察到的核壳微结构被认为是由于扩散到MOF中的速率比连接体交换慢而产生的。在这里，通过溶剂选择来控制这些过程的相对贡献，以调节壳层厚度和交换程度。这些发现使得能够根据应用需求定制MOF的微观结构。
