Metal–organic framework growth at functional interfaces: thin films and composites for diverse applications

Abstract

5Porous metal-organic frameworks (MOFs) are highly ordered crystalline materials prepared by the selfassembly of metal ions with organic linkers to yield low density network structures of diverse topology. MOFs have attracted considerable attention over the last decade due to their facile preparation, tunable pore metrics and the ease of functionalisation of their internal surfaces, such that designer frameworks with exceptional properties for application in gas-storage, separation of small molecules, heterogeneous 10 catalysis and drug delivery are becoming commonplace. For any material to find practical utility however there is a need for processing and formulation into application-specific configurations. One way to do this is to prepare composite materials where the MOF is supported on a planar substrate or some other shaped body through interaction with functional groups at the support interface. This is a rapidly developing research area, and this review provides an overview of the diverse MOF composite materials prepared up 15 to now, organised by interface type. The importance of the interface is explored within each section and while the overall emphasis is on applications of the composites, coatings and MOF-based devices, the most widely-used and successful synthetic strategies for composite formation are also presented.

In Situ Atomic/Molecular Layer-by-Layer Deposition of Inorganic–Organic Coordination Network Thin Films from Gaseous Precursors

“…9 However, these techniques might be less suited in producing thin films for applications where strong film-to-substrate adhesion and/or conformality over large-aspect-ratio substrate surfaces are required. 15 Strategies based on gas-phase thin-film deposition techniques, and in particular the state-of-the-art atomic layer deposition (ALD) technique, are believed to potentially meet the aforementioned criteria for film quality and the apparent need for industrial-level scalability. 16 Recently Stassen et al 17 used a combination of two industrially feasible gas-phase thin-film fabrication techniques, i.e.…”

Effect of Transition Metal Cations on Assembly of Highly Ordered 2D Multiporphyrin Arrays on Liquid and Solid Substrates

“…Для получения иммобилизованных на поверхности металлоорганических каркасов, ПОВМОК (Surface-Anchored Metal-Organic Frameworks, SURMOFs) используют несколько методов. [9][10][11][12][13][14] Простейший из них состоит в осаждении на подложку частиц МОК, предварительно сформированных в растворе традици-онным сольватотермальным способом. Как правило, перед этим подложка покрывается самоорганизо-ванным монослоем (СОМ) поверхностно-активного вещества, содержащего соответствующие данному МОК функциональные группы.…”
