Synthesis and anion binding studies of tris(3-aminopropyl)amine-based tripodal urea and thiourea receptors: proton transfer-induced selectivity for hydrogen sulfate over sulfate

Abstract

Tris(3-aminopropyl)amine-based tripodal urea and thiourea receptors are synthesized and investigated for anion binding, showing affinities for fluoride and the proton transfer-induced selectivity for hydrogen sulfate over sulfate in DMSO-<italic>d</italic>₆.
