Nanoarchitectonics of metal–organic frameworks having hydroxy group for adsorption, catalysis, and sensing

Functionalized metal–organic frameworks (MOFs) are very popular because of their various applications, designable functional sites, and facile preparation. MOFs composed of a hydroxy group on linkers or on grafted species are also attractive based on the possible applications of loaded –OH groups. In this review, MOFs with –OH groups (termed MOF-OHs) will be discussed in the view of both preparation and applications. Direct synthesis from linker precursors having –OH groups and post-synthetic modification will be delineated for the preparation of MOF-OHs. The applications of MOF-OHs in adsorption, catalysis, and sensing will also be dealt. This review shows that MOF-OHs can be facilely prepared via direct synthesis and post-synthetic modification; have various applications in adsorption, catalysis, etc. mainly because of the contribution of the loaded hydroxy groups. Finally, future prospects will be suggested for relevant research.
