SABRE hyperpolarizes substrates by polarization transfer from para-hydrogen in a metal complex. We have measured the signal enhancement of pyridine and its exchange rate in various Ir(NHC)(Py)3(H)2 complexes to gain insight into their dependence on the N-Heterocyclic Carbene (NHC) ligand's steric and electronic properties.
SABRE 通过金属配合物中仲氢的极化转移使底物极化。我们已经测量了吡啶及其在各种[Ir（NHC）（Py）3（H）2]（+）配合物中的交换速率的信号增强，以深入了解它们对 N-杂环卡宾（NHC）配体的立体和电子性质的依赖性。
