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

Germanium-73 is an extremely challenging nucleus to examine by solid-state NMR spectroscopy, due to its unfavorable NMR properties. Through the use of an ultrahigh (21.1 T) magnetic field, a systematic study of a series of organogermanes was carried out.
