An interesting reversible shape and structure transformation between two types of two-dimensional (2D) metal–organic frameworks (MOFs) has been successfully achieved by the spray method. The ability to precisely control the morphology and structure of 2D MOFs is also developed by altering the amount of MOF precursors and reversing the spray order. Meanwhile, the mechanism of the transformation between two MOFs is studied and conversion is induced by the change of the acidity in the reaction system. In addition, the prepared non-interpenetrate CuBDC twists exhibit more remarkable catalytic performance in C–S coupling reaction than Cu(BDC)(DMF) nanosheets owing to the more unsaturated coordination copper active sites from the non-interpenetrate structure. The catalytic result reveals the relationship between structure and function.

二维金属有机骨架的结构和形态转变，同时采用喷雾法进行受控制备。

通过喷涂方法已成功实现了两种类型的二维（2D）金属-有机骨架（MOF）之间有趣的可逆形状和结构转换。通过更改MOF前体的数量并反转喷涂顺序，还可以开发出精确控制2D MOF的形态和结构的功能。同时，研究了两个MOF之间的转化机理，并通过反应体系中酸度的变化诱导了转化。此外，由于非互穿结构中铜的活性位点更多，因此制备的非互穿CuBDC扭曲物在Cu-S偶联反应中比Cu（BDC）（DMF）纳米片表现出更出色的催化性能。催化结果揭示了结构和功能之间的关系。
