Improved Dynamic Nuclear Polarization Surface-Enhanced NMR Spectroscopy through Controlled Incorporation of Deuterated Functional Groups
In a spin: The use of deuterated surface passivation agents is shown to restore dynamic nuclear polarization (DNP) surface-enhanced NMR signals that are reduced in substrates containing methyl groups, while still protecting sensitive sites on the surface (see picture). Furthermore, apolar groups such as [D9]-trimethylsiloxy (TMS) repel radicals (yellow) away from the surface, thus diminishing detrimental paramagnetic effects induced by radical proximity.
