摘要

Abstract > Dynamic nuclear polarization (DNP) is a technique to polarize the nuclear spin population. As a result of the hyperpolarization, the NMR sensitivity of the nuclei in molecules can be dramatically enhanced. Recent application of the hyperpolarization technique has led to advances in biochemical and molecular studies. A major problem is the short lifetime of the polarized nuclear spin state. Generally, in solution, the polarized nuclear spin state decays to a thermal spin equilibrium, resulting in loss of the enhanced NMR signal. This decay is correlated directly with the spin‐lattice relaxation time T <sub>1</sub> . Here we report [ 13 C,D <sub>14</sub> ] tert ‐butylbenzene as a new scaffold structure for designing hyperpolarized 13 C probes. Thanks to the minimized spin‐lattice relaxation ( T <sub>1</sub> ) pathways, its water‐soluble derivative showed a remarkably long 13 C T <sub>1</sub> value and long retention of the hyperpolarized spin state. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden"

动态核偏振(DNP)是一种偏振核旋转群体的技术。由于超极化,可以显着增强分子中核的NMR敏感性。最近的超极化技术的应用导致生化和分子研究进展。主要问题是偏振核旋转状态的短寿命。通常,在溶液中,偏振核自旋状态衰减到热旋转平衡,导致增强的NMR信号损失。这种衰减与旋转格子松弛时间直接相关 t </ i> <sub> 1 </ sub> 。在这里我们报告[ 13 </ sup> 光盘 <sub> 14
