NMR signal enhancement > 50000 times in Fast Dissolution Dynamic Nuclear Polarization
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...

| Sumario: | 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. |
