Non-aqueous solvents for DNP surface enhanced NMR spectroscopy

Zagdoun, A., et al., Non-aqueous solvents for DNP surface enhanced NMR spectroscopy. Chem Commun (Camb), 2012. 48(5): p. 654-6.

A series of non-aqueous solvents combined with the exogenous biradical bTbK are developed for DNP NMR that yield enhancements comparable to the best available water based systems. 1,1,2,2-tetrachloroethane appears to be one of the most promising organic solvents for DNP solid-state NMR. Here this results in a reduction in experimental times by a factor of 1000. These new solvents are demonstrated with the first DNP surface enhanced NMR characterization of an organometallic complex supported on a hydrophobic surface.
