17O NMR in MOFs

Cover article in the Journal of Physical Chemistry C (August 28/13)

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-900state 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.


Dr. William (Bill) Schneider (1915 - 2013) (March 21/13)

Chemistry Icon Dies at 97

Dr. William (Bill) George Schneider passed away peacefully in Ottawa on February 18, 2013 at the age of 97. Dr. Schneider had a distinguished career in science at the National Research Council Canada. His pioneer work in research on Nuclear Magnetic Resonance (NMR) led to widespread use of diagnostic imagery (MRI) and was recognized at the opening of the W.G. Schneider Building at NRC for NMR research in 2006. He was President of the National Research Council Canada from 1967 to 1980, a Fellow of the Royal Societies of London and Canada, and an Officer of the Order of Canada.

Cover article in Angewandte Chemie (Nov 18/10)

acie2010

Low concentration and poor sensitivity often hinder or make impossible solid-state 17O NMR in large biomolecular systems. In this cover article in Angewandte Chemie Gang Wu (Queen’s) and co-workers from the University of Ottawa and NRC Canada show that at an ultrahigh magnetic field of 21 T the high quality solid-state 17O NMR spectra can be obtained for large protein–ligand complexes of up to 300 kDa in size. Complementary multinuclear 17O, 27Al, and 13C NMR data obtained in this work have aided in the structural refinement for an ovotransferrin bound Al-oxalate complex.

Opportunities for studying polymorphs and cement-based materials via Ca-43 solid-state NMR

June 11, 2010, University of Ottawa

Calcium is an important component in diverse materials and biochemicals. However, NMR spectroscopy of the only spin-active calcium isotope, Ca-43, is notoriously challenging due to its low natural abundance (0.14 %), low resonance frequency, and quadrupolar nature. Recently, researchers from the University of Ottawa, the NRC Steacie Institute for Molecular Sciences (SIMS-NRC), and Dalhousie University have independently reported advances in studies of inorganic polymorphs and cement-based materials using Ca-43 solid-state NMR spectroscopy.

"In spite of the great complexity of the calcium silicate chemistry involved in the hydration of Portland cement, we have shown that Ca-43 solid-state NMR provides useful new insights into cement chemistry", says Igor Moudrakovski (SIMS-NRC) of his collaboration with the Institute for Research in Construction (SIMS-IRC). Josef Zwanziger (Dalhousie) and his academic and industrial partners have similarly applied Ca-43 NMR in their project on the development, optimization and commercialization of high performance cement based composite materials.

Zwanziger explains, "we are trying to understand the nature of the composite-cement interface, and the mechanisms of toughening and strengthening in concrete composites. Calcium NMR is one of the many tools which is shedding light on the nature of the interface." At the University of Ottawa, David Bryce and his research group have demonstrated the utility of calcium NMR in understanding polymorphism in solids. This work has implications for understanding biomaterials as well as inorganic materials.

Because Ca-43 NMR in solid state requires a very strong magnetic field for sensitivity reasons, all these experiments were carried out at the National Ultrahigh-Field NMR Facility for Solids, a national user facility managed by the University of Ottawa and housed on NRC's Ottawa campus, which houses Canada's only 21.1 T (900 MHz) NMR spectrometer.

The latest calcium NMR research has been published in PCCP and J. Am. Chem. Soc., and a perspective on the state of the field is now available in Dalton Transactions (Bryce, 2010).

A research team from the University of Calgary and the NRC Steacie Institute for Molecular Sciences (Ottawa) has published a cover article in Nature Chemistry

J.A. Hurd, R. Vaidhyanathan, V. Thangadurai, C.I. Ratcliffe, I.L. Moudrakovski and G.K.H. Shimizu,
"Proton Conduction at 150°C in a Nanoporous Metal-Organic Framework," Nature Chemistry 1 (2009) 705-710. http://dx.doi.org/10.1038/nchem.402

"Materials built from metal centres and organic ligands have traditionally attracted attention for their channels' host–guest properties. Now, controlling the occupancy of the channels by guest molecules has resulted in a framework that conducts protons under anhydrous conditions and acts as a gas-tight membrane, offering a promising approach to fuel-cell electrolytes."

Solid-state NMR spectroscopy was instrumental in this research.

The paper is also accompanied by the Nature's commentary:

chem comm Unique instrumentation available at the 900 NMR Facility allows our users to deal with systems and nuclei inaccessible before with NMR at lower fields. One example is 73Ge NMR in solids which was previously limited only to highly symmetric environments. In this cover article just published by Chemical Communications a research team from the University of Manitoba and NRC-SIMS is reporting natural abundance 73Ge NMR spectra in much more challenging amorphous and crystalline germanium oxides. Work continues on even more complex glasses and crystalline phases to address long-standing fundamental questions in glass science, such as the ‘‘germanate anomaly’’.
