This article reports the synthesis and the study as polarizing agent for fast dissolution DNP of a novel mixed biradical with a BDPA and TEMPO radical units covalently bound by an ester group (BDPAesterTEMPO). Such a biradical exhibits an extremely high DNP NMR enhancement > 50000 which constitutes one of the largest signal enhancement observed so far, to the best of our knowledge.
