Abstract:
Metal-organic frameworks (MOFs) have become the largest branch of porous materials. Although MOFs have many applications, the local structures of metal ions, organic linkers, and guest behaviors underpinning the MOF properties are often not well understood at molecular level. Solid-state NMR (SSNMR) spectroscopy is a powerful tool for MOF characterization as it provides nuclide specific information and is sensitive to short-range ordering and dynamics.
In this talk, Prof. Yining Huang will report very recent studies on MOF characterization using both high-resolution and ultrawide-line SSNMR. Their work has focused on directly probing metal center environments by interrogating metal ions (67Zn, 91Zr, 65/63Cu, 209Bi) via their SSNMR spectra; examining local structure around halogens in halide-organic hybrid MOFs by 35Cl and 127I SSNMR; monitoring the behavior of adsorbed guest molecules. The NMR results lead to a deeper understanding of the structure-properties-function relationships in MOF systems.
