Abstract
Water soluble squaramide macrocycles (MSQs) display high sulfate binding affinities in aqueous DMSO mixtures. The introduction of pyridine spacers into the macrocycles resulted in increased sulfate binding affinity in comparison to compounds with benzene spacers. [3]MSQ 6 was found to be a selective ligand for SO42- in highly competitive conditions and over a wide pH range (3.2-14).
摘要
水溶性方酰胺大环（MSQs）在含水 DMSO 混合物中显示出高硫酸根结合亲和力。与具有苯环间隔基的化合物相比，将吡啶间隔基引入大环中导致硫酸根结合亲和力增加。[3]在高竞争条件下和宽 pH 范围（3.2-14）下，发现 MSQ6 是 SO42-的选择性配体。
