Receptors for sulfate that function across a wide pH range in mixed aqueous–DMSO media

Abstract

Water soluble squaramide macrocycles (MSQs) display high sulfate binding affinities in aqueous DMSO mixtures. The introduction of pyridine spacers into the macrocycles resulted in increased sulfate binding affinity in comparison to compounds with benzene spacers. [3]MSQ 6 was found to be a selective ligand for SO42− in highly competitive conditions and over a wide pH range (3.2–14).
