Solid-State NMR Studies of Small Molecule Adsorption in Metal-Organic Frameworks (MOFs)
Metal-organic frameworks (MOFs) represent a modern class of porous materials with high flexibility and tunability of properties. Solid-state NMR (SSNMR) investigations can provide numerous pieces of information toward their structural characterization. The subject of this article is to present the results that have been obtained from inclusion of small molecules into the pores with regard to their dynamics inside the pores and their interaction with the host framework. Molecules like water and carbon dioxide are typical candidates for adsorption. Also 129Xe NMR is performed to get information on pore sizes. Incorporation of other molecules like nitric oxide and metallic particles is discussed as well.
