Abstract
Europium is an f-block metal with two easily accessible oxidation states (+2 and +3) that have vastly different magnetic and optical properties from each other. These properties are tunable using coordination chemistry and are useful in a variety of applications, including magnetic resonance imaging, luminescence, and catalysis. This review describes important aspects of coordination chemistry of Eu from the Allen Research Group and others, how ligand design has tuned the properties of Eu ions, and how those properties are relevant to specific applications. The review begins with an introduction to the coordination chemistry of divalent and trivalent Eu followed by examples of how the coordination chemistry of Eu has made contributions to magnetic resonance imaging, luminescence, catalysis, and separations. The article concludes with a brief outlook on future opportunities in the field.
铕是一种 f 块金属,具有两种容易获得的氧化态(+2 和 +3),这两种氧化态的磁性和光学特性大不相同。这些性质可通过配位化学进行调节,并可用于磁共振成像、发光和催化等多种应用。本综述介绍了艾伦研究小组和其他研究小组在 Eu 配位化学方面的重要研究成果、配体设计如何调整 Eu 离子的性质,以及这些性质与特定应用的相关性。文章首先介绍了二价和三价 Eu 的配位化学,然后举例说明 Eu 的配位化学如何为磁共振成像、发光、催化和分离做出贡献。文章最后简要展望了该领域的未来机遇。
