报告摘要：

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.

We have examined various MOF systems using a variety of NMR techniques. In this talk I will talk about our work on directly probing metal center environments by interrogating ⁶⁷Zn, ²⁵Mg, ¹¹⁵In, ⁹¹Zr, ^71/69Ga, ¹²⁹La, ³⁹K, ⁴³Ca, ^47/49Ti, ^65/63Cu, ²⁰⁹Bi via their SSNMR spectra; examining local structure around organic linkers by ¹H, ¹³C, ¹⁷O, 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. Furthermore, SSNMR can also serve as a guiding tool in MOF chemistry, and illustrative examples of post-synthetic modifications will be presented.
