Metal-organic frameworks (MOFs) are a class of porous crystalline materials which have shown potential for a range of applications. Their structure, consisting of organic linkers connecting clusters of metal atoms, creates a phase-space with unparalleled diversity -over 100,000 MOFs have been experimentally synthesized to date, and several million more hypothetical structures have been identified. MOFs are a subject of intense research due to their record-breaking levels of porosity, - 35 modular construction enabling fine-tuning of metal and linker chemistry, and the resultant diversity in terms of materials properties. Accordingly, there have been many studies focusing on the applicability of MOFs to industrially important small molecule separation and storage applications.
