Abstract

The neutral anion receptor 1 was synthesized by an easy method with high yield. The binding properties of anions with 1 were examined by UV-vis and ¹H NMR spectroscopy. Receptor 1 can form a 1 : 2 complex with F⁻, and 1 : 1 complexes with AcO⁻ and H₂PO₄⁻ anions, respectively, by multiple hydrogen-bonding interactions. There is an observable colour change for the complex formed by 1 and F⁻.
