biostudies-literatureUnknown34(5)Bumstead AMMelt-quenched metal-organic framework (MOF) glasses have gained significant interest as the first new category of glass reported in 50 years. In this work, an amine-functionalized zeolitic imidazolate framework (ZIF), denoted ZIF-UC-6, was prepared and demonstrated to undergo both melting and glass formation. The presence of an amine group resulted in a lower melting temperature compared to other ZIFs, while also allowing material properties to be tuned by post-synthetic modification (PSM). As a prototypical example, the ZIF glass surface was functionalized with octyl isocyanate, changing its behavior from hydrophilic to hydrophobic. PSM therefore provides a promising strategy for tuning the surface properties of MOF glasses.Chemistry of materials : a publication of the American Chemical Society2187-2196https://www.ebi.ac.uk/biostudies/studies/S-EPMC9100367biostudies-literaturePost-Synthetic Modification of a Metal-Organic Framework Glass.PMC9100367Bennett TDEvans RCPakamore IThorne MFKeeble DSRichards KDMcHugh LNCastillo-Blas CKeen DABoyadjieva SSBumstead AMForgan RSSapnik AFfalsePost-Synthetic Modification of a Metal-Organic Framework Glass.Melt-quenched metal-organic framework (MOF) glasses have gained significant interest as the first new category of glass reported in 50 years.
