Monofunctionalized Bambus[6]urils and Their Conjugates with Crown Ethers for Liquid–Liquid Extraction of Inorganic Salts

Abstract

Bambusurils are a growing family of macrocyclic anion receptors. In this Letter, we present the first syntheses of monofunctionalized bambusurils and their use for the preparation of heteroditopic bambusuril-crown ether conjugates suitable for the extraction of ion pairs from water to chloroform.
