Following a late-stage functionalization strategy, a series of heteroditopic cryptand receptors were prepared – in three steps only from 1,4-dioxane. As evidenced by ¹H-NMR spectroscopic and solid state analyses, these polyamide-crown ether conjugates present general ion pair binding capacity towards salts of monovalent cations and linear triatomic anions.
