hetero-capsules 1·2 resulting from the ionic interactions between positively charged flexible anilinehydrochloride 1 and negatively charged phosphonate 2 having rigid homooxacalix[3]arene units. The formation of the molecular capsules was studied by NOESY, DOSY NMR spectroscopy and ESI-Mass spectrometry. The watersolubility of the capsules is improved by the introduction of mono- or triethylene glycol substituents
