We demonstrate how a single-crystal to single-crystal transformation resulting from bridging-linker replacement is possible in extended 2D and 3D metal-organic frameworks (MOFs) by introducing pillared paddlewheel MOF structures into a solution containing dipyridyl linkers. No lateral movement of the layers was observed during this transformation, creating a templating effect from the "parent" structure to the "daughter" structure. A previously unattainable structure was obtained by a two-step synthetic method utilizing the bridging-linker replacement transformation method. Additionally, a bridging-linker insertion was observed when excess linker was used with the 2D MOF structure, inducing an overall 2D to 3D transformation.

金属-有机骨架的逐步合成：结构有机接头的替代

我们展示了如何通过将柱状桨轮 MOF 结构引入包含联吡啶连接器的溶液中，在扩展的 2D 和 3D 金属有机框架 (MOF) 中实现由桥接连接器替换引起的单晶到单晶转变。在此转换过程中没有观察到层的横向移动，从而产生了从“父”结构到“子”结构的模板效应。以前无法获得的结构是通过两步合成方法获得的，该方法利用了桥接头置换转化方法。此外，当过量的接头与 2D MOF 结构一起使用时，会观察到桥接头插入，从而诱导整体 2D 到 3D 转换。
