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.
