Tripodal cyanurates as selective transmembrane Cl− transporters

Abstract

Tris-carboxyamide and tris-sulfonamide-based anion transporters with a cyanuric acid core are reported. Interestingly, Cl⁻ ion binding and transmembrane transport properties of carboxyamides are better compared to those of their tris-sulfonamide analogs. The carboxyamide derivatives act as mobile carriers of Cl⁻ and exchange anions via antiport mechanism.
