Abstract

We report the first example of chirality induction in a large-sized crown ether congener with bis(arylthiourea) units, which serve as an anion binding site. The phenomenon arises via an achiral ion-pair coordinated self-assembly in which intermolecular head-to-tail hydrogen bonding interactions occur between the thiourea units in the solid state.
