Cover article in the Journal of Physical Chemistry C

Peng He, Jun Xu, Victor V. Terskikh, Andre Sutrisno, Heng-Yong Nie, and Yining Huang, "Identification of Non-equivalent Framework Oxygen Species in Metal-organic Frameworks by 17O Solid-state NMR," Journal of Physical Chemistry C 117 (2013) 16953–16960. (Cover Article) http://dx.doi.org/10.1021/jp403512m

17O solid-state NMR spectra provide signatures of various oxygen species in metal-organic frameworks. We successfully prepared several prototypical 17O -enriched metal-organic frameworks (MOFs). Due to the diversity of MOF-based materials, different types of MOFs require different isotopic enrichment methods to effectively incorporate 17O from 17O-enriched H2O. Several synthetic strategies for 17O-enrichment were discussed. Using these 17O-enriched MOFs, we were able to acquire 17O solid-state NMR spectra at a magnetic field of 21.1 T. They provide distinct spectral signatures of various key oxygen species commonly existing in representative MOFs.

This cover article features results obtained using the 21.1 T solid-state NMR spectrometer at the National Ultrahigh-Field NMR Facility for Solids (Ottawa, ON). If you are interested in using this spectrometer in your research please contact the Facility Manager http://nmr900.ca
