Pinto, L.F., et al., NMR signal enhancement of >50 000 times in fast dissolution dynamic nuclear polarization. Chem Commun (Camb), 2017. 53(26): p. 3757-3760.
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.
