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.

金属-有机框架接头交换中的溶剂选择允许微观结构控制

链接器交换是一种广泛应用的、稳健的技术,用于合成后金属有机框架 (MOF) 的细化。假设在某些条件下观察到核壳微结构是由于扩散到 MOF 的速度比连接器交换慢。在这里,这些过程的相对贡献是通过溶剂选择来控制的,以调节壳厚度和交换程度。这些发现允许根据应用定制 MOF 微结构。
