Solid State Nmr Spectroscopic Studies Of Metal-Organic Frameworks, Peng He

Electronic Thesis and Dissertation Repository

Metal−organic frameworks (MOFs) are a class of novel porous materials with a wide range of chemical applications. Structural characterization is important because understanding the relationship between the properties of these industrially relevant materials and their structures allows one to develop new applications and improve current performance. In this thesis ¹⁷O solid state NMR (SSNMR) spectroscopy is used to differentiate chemically and, under favorite circumstances, crystallographically nonequivalent oxygens and to follow the phase transitions in MOF-based materials. Several cost-effective approaches were used to prepare ¹⁷O-labelled MOFs. The metal centers of MOFs, including ^47/49Ti, ⁶⁷Zn, ⁹¹Zr, ^{115 …}
