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.

The tris(thiourea) receptor, L, encapsulates a trivalent phosphate ion within a rigidified -stacked dimeric capsular assembly, allowing for the formation of strong H-bonds and a new set of signals in (1)H NMR titration experiments
