An anion‐exchange strategy was used to prepare two helical structures made up of cucurbituril and asymmetric copper( II ) complexes containing 8‐hydroxyquinoline‐5‐sulfonate and 3,5‐diiodosalicylate (right half of picture) or 3‐iodobenzoate (left half). The shape‐matching interactions between cucurbituril and the copper complexes were assisted by the iodo substituents.
