NMR signal enhancement of > 50 000 times in fast dissolution dynamic nuclear polarization Pinto, L.F. Marín Montesinos, Ildefonso Lloveras, Vega Muñoz-Gómez, José Luis Pons Vallès, Miquel Veciana, Jaume Vidal Gancedo, José Polarització (Física nuclear) Spin (Física nuclear) Polarization (Nuclear physics) Nuclear spin 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 >50 000 times, which constitutes one of the largest signal enhancements observed so far, to the best of our knowledge 2019-07-30T12:01:53Z 2019-07-30T12:01:53Z 2017-03-03 2019-07-30T12:01:53Z info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Versió postprint del document publicat a: https://doi.org/10.1039/c7cc00635g Chemical Communications, 2017, vol. 53, num. 26, p. 3757-3760 https://doi.org/10.1039/c7cc00635g (c) Pinto, L.F. et al., 2017 info:eu-repo/semantics/openAccess Royal Society of Chemistry Articles publicats en revistes (Química Inorgànica i Orgànica)
