Abstract
The tris(thiourea) receptor, L, in the presence of excess H(2)PO(4)(-) has been found to encapsulate a trivalent phosphate ion within a π-stacked dimeric capsular assembly of the receptor with twelve strong H-bonds via deprotonation, as evident from the origin of a new set of signals in the (1)H NMR titration experiments.
摘要
在存在过量 H(2)PO(4)(-)的情况下，已发现三(硫脲)受体 L 可以通过去质子化作用将三价磷酸离子封装在受体的π堆积二聚体胶囊组装体内，其中 12 个强氢键可作为证据，这可以从 (1)H NMR 滴定实验中出现的新信号组得到证明。
