Fecha de publicación: | 4-abr-2017 | Editor: | Royal Society of Chemistry (UK) | Citación: | Chemical Communications 53(26): 3757-3760 (2017) | Resumen: | Herein, we report the synthesis and the study of a novel mixed biradical with BDPA and TEMPO radical units that are covalently bound by an ester group (BDPAesterTEMPO) as a polarizing agent for fast dissolution DNP. The biradical exhibits an extremely high DNP NMR enhancement of >50[thin space (1/6-em)]000 times, which constitutes one of the largest signal enhancements observed so far, to the best of our knowledge. | Versión del editor: | http://dx.doi.org/10.1039/C7CC00635G | URI: | http://hdl.handle.net/10261/151394 | DOI: | 10.1039/C7CC00635G | ISSN: | 1359-7345 |
