A series of mono- or bis-sulfonylthioureas has been synthesized via nucleophilic substitution of potassium sulfonamides and sodium dithiocarbamate in water under mild conditions, and their properties as anion receptors in the absence and presence of K+ have been investigated by 1H NMR spectroscopy. It was found that calix[4]crown-5 derivative 10 shows much higher selective complexation capability with H2PO4 - in the presence of K+ than in the absence of K +, which indicates the physical dimension of K+ and H 2PO4-, respectively, matched the corresponding cavity of the host compound.
