並列タイトル等DNP experiments on BDPA-doped solutions with different organic solvents
一般注記In order to investigate the experimental technique and the high magnetic field effect in the dynamical nuclear polarization (DNP) experiments, the X-band 1H-DNP experiments have been performed on a organic solution of a,y-bisdiphenylene-β-phyenylallyl (BDPA) radical at room temperature. Because BDPA-doped toluene solution evaporated immediately during sub-THz irradiation, we tried DNP experiments with changing the solvent from toluene to benzene. As a result, we obtained similar DNP effects on the two solutions. We can expect that benzene solution is an appropriate sample for sub-THz DNP experiments. Further, we performed pulse-ESR experiments in order to measure electron relaxation times. We discuss the power dependence of DNP enhancement with measured relaxation times.
