我们演示了如何在扩展的2D和3D金属有机框架（MOFs）中通过将柱撑桨轮MOF结构引入含有联吡啶连接体的溶液中来实现由桥接连接体替换导致的单晶到单晶的转变。在这种转变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。一个以前无法达到的结构，通过两步合成方法，利用桥接接头置换转化方法获得。此外，当过量的接头与2D MOF结构一起使用时，观察到桥接接头插入，从而诱导总体2D到3D的转化。
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 paddle-wheel 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.
