Highly selective hydrophilic ligands were believed to be an efficient way to overcome the massive amount of hazardous organic solvent used in the liquid–liquid extraction process and stood as a new frontier in the Lns(III)/Ans(III) partition. Current reported hydrophilic ligands suffer from harsh preparation conditions, inferior extraction performances, limited available chemical structures, and inability to carry out extraction under high acidity. In this article, we report a simple yet efficient carboxylic group modified phenanthroline-diimide ligand which displayed unexpected Lns(III)/Ans(III) and Ans(III)/Ans(III) separation capabilities in 1.5 M HNO₃. Unique dimeric architectures for Eu(III) complexes were observed, which could be the origin of the outperforming selectivity and acid resistance. We believe this crystal engineering approach could inspire a renaissance in searching for new functional groups and coordination modes for efficient, high-acid-tolerance Lns(III)/Ans(III) separation ligands.

一种简单而高效的亲水性菲咯啉基配体，用于在高酸度下选择性分离 Am(III)

高选择性亲水配体被认为是克服液-液萃取过程中使用的大量有害有机溶剂的有效方法，并成为 Lns(III)/Ans(III) 分配的新前沿。目前报道的亲水配体存在制备条件苛刻、萃取性能较差、可用化学结构有限、无法在高酸度下进行萃取等问题。在本文中，我们报道了一种简单而有效的羧基修饰的菲咯啉二酰亚胺配体，该配体在 1.5 M HNO 3 中表现出意想不到的 Lns(III)/Ans(III) 和 Ans(III)/Ans(III) 分离_能力。观察到 Eu(III) 配合物独特的二聚体结构，这可能是其优异的选择性和耐酸性的根源。我们相信，这种晶体工程方法可以激发寻找新官能团和配位模式的复兴，以实现高效、高耐酸的 Lns(III)/Ans(III) 分离配体。
