Abstract

Two anion receptors 1 and 2 with a nitrophenyl group as a signaling group and urea/thiourea as a binding group were synthesized and their anion binding abilities were examined. The receptor 1 formed the hydrogen-bonded complex with various anions except fluoride. However, the receptor 2 immediately formed deprotonated receptor with various anions. Therefore, they operated based on a hydrogen bonding and an acid-base equilibrium. In addition, the receptor 1 proved to be an efficient and selective naked-eye detector for the fluoride ion.
