(thio)urea- and amide-functionalized quinoline-based anion receptors towards halide anions was investigated in detail in CDCl3 and [D6]DMSO solutions by using 1H and 19F NMR spectroscopic methods. The electronic, solvent, and fluoro-substitution effects were studied. The (thio)urea- and amide-functionalized quinoline-based anion receptors showed medium to strong anion affinity and good selectivity in solution
通过使用 1H 和 19F NMR 光谱方法,在 CDCl3 和 [D6]DMSO 溶液中详细研究了(硫)脲和酰胺官能化喹啉基阴离子受体对卤化物阴离子的结合行为。研究了电子、溶剂和氟取代效应。(硫)脲和酰胺官能化的喹啉基阴离子受体在溶液中显示出中等至强的阴离子亲和力和良好的选择性。获得了关键化合物的单晶,并通过X射线衍射光谱进行了研究。
