Iodine‐Assisted Assembly of Helical Coordination Polymers of Cucurbituril and Asymmetric Copper(<scp>II</scp>) Complexes

Abstract

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.
