摘要: A series of neutral anion receptors with one to three thiourea arms were synthesized and their binding tetrabutylammonium chloride, acetate, dihydrogen phosphate salts in aqueous DMSO mixtures was examined. The three-armed host found strongly selectively bind H2PO4(-) even solutions containing up 30% water. This enabled the salt be extracted from water into chloroform its dibasic form despite high heat hydration HPO4(2-).
