Abstract
The hydration behaviour of coordination complexes is important for understanding their roles as bio-imaging agents. Determination of hydration is difficult, and various optical and NMR-based techniques have been used. Here we use EPR spectroscopy to unambiguously demonstrate that a -butyl-pyridyl-functionalised Er DOTA derivative coordinates water, while its methylphosphinate analogue does not.
摘要
配合物的水合行为对于理解它们作为生物成像剂的作用非常重要。水合的测定很困难，已经使用了各种基于光学和 NMR 的技术。在这里，我们使用 EPR 光谱学明确地证明了 -丁基-吡啶基功能化的 Er DOTA 衍生物与水配位，而其甲基膦酸盐类似物则不与水配位。
