Flexibility in Metal-Organic Frameworks: A Fundamental Understanding
Christia Jabbour, Noor Aljammal, Tatjána Juzsakova, Francis Verpoort
Metal-organic frameworks (MOFs) had until recently the reputation of being one of the most critical porous materials. Their flexibility, however, has gained a lot of attention due to the wide selection of possible combinations between metal nods and/or ligands. Nonetheless, it is not always easy to identify the source of flexibility. This chapter focuses on the origin of flexibility, and the substantial geometrical changes that can occur due to external stimuli, such as temperature, pressure, light, gas or solvent adsorption. Flexibility control methods have also been discussed along with possible characterization techniques to help to identify the source of flexibility. Practical applications of flexible MOFs in gas separation and other processes are also discussed. In this respect, several prized examples covered by the literature are present to help in a comprehensive understanding in terms of design and structure tunability of flexible MOFs.
