iii-Phosphorylated cavitands incorporating an N-methylpyridinium guest moiety as the fourth bridging unit form supramolecular associations by inclusion of the charged CH3N(+)-pyridinium head into a neighboring host cavity. The dimeric association is favored in solution and was characterized by NMR, mass spectrometry, DOSY experiments, and single crystal X-ray analysis.
