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 - .
