The preparation of crystalline, ordered thin films of metal-organic frameworks (MOFs) will be a critical process for MOF-based nanodevices in the future. MOF thin films with perfect orientation and excellent crystallinity were formed with novel nanosheet-structured components, Cu-TCPP [TCPP = 5,10,15,20-tetrakis(4-carboxyphenyl)porphyrin], by a new "modular assembly" strategy. The modular assembly process involves two steps: a "modularization" step is used to synthesize highly crystalline "modules" with a nanosized structure that can be conveniently assembled into a thin film in the following "assembly" step. With this method, MOF thin films can easily be set up on different substrates at very high speed with controllable thickness. This new approach also enabled us to prepare highly oriented crystalline thin films of MOFs that cannot be prepared in thin-film form by traditional techniques.
未来，金属-有机骨架（MOF）晶体、有序薄膜的制备将成为 MOF 基纳米器件的关键工艺。通过一种新的“模块组装”策略，使用新型纳米片结构组件 Cu-TCPP[TCPP=5,10,15,20-四（4-羧基苯基）卟啉]形成具有完美取向和优异结晶度的 MOF 薄膜。模块组装过程包括两个步骤：“模块化”步骤用于合成具有纳米结构的高结晶性“模块”，这些模块可以在以下“组装”步骤中方便地组装成薄膜。使用这种方法，可以非常快速地将 MOF 薄膜设置在不同的基底上，并且厚度可控。这种新方法还使我们能够制备传统技术无法制备的高度取向的 MOF 晶体薄膜。
