合成了一种以6，6 '-双（1H-1，2，3-三唑-4-基）-2，2'-联吡啶（BTzBP）为结构核心的亲水性配体。在萃取剂配体上添加水溶性基团的效果已被广泛研究，以促进4f和超铀5 f元素的有效分配，用于处理乏核燃料。软的N-供体配体对三价锕系元素表现出比三价镧系元素更大的结合亲和力，使得BTzBP配体成为寻找在工业规模上使用的萃取剂的理想候选物。迄今为止，疏水BTzBP已显示出可能有利于核废料处理条件的物理和化学性质。然而，亲水性BTzBP尚未被报道。在本文中，我们显示了亲水性BTzBP配体的合成，其特征在于连接到联吡啶环的阳离子水增溶基团。
A hydrophilic ligand that contains only C, H, O, and N substituents and uses a 6,6 '-bis(1H-1,2,3-triazol-4-yl)-2,2 '-bipyridine (BTzBP) structural core has been synthesized. The effect of adding water-soluble groups onto extractant ligands has been extensively studied to facilitate the efficient partitioning of 4f and transuranic 5f elements for the treatment of spent nuclear fuel. Soft, N-donor ligands exhibit greater binding affinities for the trivalent actinides over the trivalent lanthanides, making BTzBP ligands an ideal candidate in the search for extractants to be used on an industrial scale. To date, hydrophobic BTzBPs have been shown to exhibit physical and chemical properties that might be conducive to nuclear waste processing conditions. However, hydrophilic BTzBPs have yet to be reported. Herein, we show the synthesis of a hydrophilic BTzBP ligand featuring cationic water solubilizing groups attached to the bipyridal rings.
