Abstract

Chiral bis(diimine) ligands (derived from chiral enantiopure diamines and 2-formylpyridine) enantioselectively self-assemble with an iron (ii) salt to either the tetrahedral cage molecule ΔΔΔΔ-[Fe4L6]8+ or its enantiomer, ΛΛΛΛ-[Fe4L6]8+. These versatile water-soluble capsules are capable of binding a wide range of organic guests in their large hydrophobic cavities. Among these guests is the neurotoxic insecticide dichlorvos, for which the ΔΔΔΔ-[Fe4L6]8+ coordination capsule serves as a competent supramolecular catalyst for its hydrolysis.
