The preparation of crystalline, ordered thin films of metal鈥搊rganic 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鈥揟CPP [TCPP = 5,10,15,20-tetrakis(4-carboxyphenyl)porphyrin], by a new 鈥渕odular assembly鈥?strategy. The modular assembly process involves two steps: a 鈥渕odularization鈥?step is used to synthesize highly crystalline 鈥渕odules鈥?with a nanosized structure that can be conveniently assembled into a thin film in the following 鈥渁ssembly鈥?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.
