隐酸盐[Eu-II(2.2.2)(H2O)(2)](2+)在Po(2)响应型核磁共振造影剂的应用中表现出一些有趣的特征：相对稳定的抗氧化性，它有两个内球水分子，水交换和电子自旋弛豫速率处于最佳范围，以获得高的质子弛豫度，前提是旋转也被优化。
The cryptate [Eu-II (2.2.2)(H2O)(2)](2+) displays several interesting features with respect to pO(2) responsive MRI contrast agent applications: it is relatively stable against oxidation, it has two inner sphere water molecules, and the water exchange and electron spin relaxation rates are in the optimal range to attain high proton relaxivities, provided the rotation is also optimized.
