The complexation of actinide cations by polyoxometalates (POMs) has been extensively studied over the past 50 years. In this perspective article, we present the rich structural diversity of actinide-POM complexes and their contribution to the extension of our knowledges of actinide chemistry, especially regarding aspect of their redox chemistry, as well as application for the capture and separation of these cations in the context of nuclear fuel remediation. These heterometallic assemblies have also proven highly valuable as model for heterogeneous systems based on actinides supported by metal oxide surfaces. In particular, activation of the An-O bond of actinyl fragments upon complexation with lacunary POMs has been reported, creating opportunities for future developments regarding the reactivity of these heterometallic assemblies.
在过去的50年里，多金属氧酸盐（POMs）与锕系阳离子的络合作用得到了广泛研究。在这篇展望文章中，我们展示了锕系 - POM络合物丰富的结构多样性，以及它们对扩展我们对锕系化学知识的贡献，特别是在其氧化还原化学方面，以及在核燃料修复背景下用于捕获和分离这些阳离子的应用。这些异金属组装体作为基于金属氧化物表面负载的锕系元素的多相体系模型也已被证明具有很高的价值。特别地，已经报道了与缺位POM络合时锕酰片段的An - O键活化，为这些异金属组装体的反应性未来发展创造了机会。
