New molecules derived from cucurbituril with either a propanediurea unit or cyclohexane moieties have been synthesized. Their solubility in pure water increased with the number of these nonclassical units. This can be explained in terms of changes in intermolecular C–H···O hydrogen bonding rather than in the molecular shape.
