Abstract

Cyclophanes having two thiourea groups were synthesized and their anion binding ability was examined by titration method using ¹ H-NMR spectroscopy. Strong and selective anion binding of the preorganized cyclic receptors was observed in the general order of H ₂ PO ₄ > CH ₃ COO ^- > Cl ^- > HSO ₄ ^- > Br ^- .
