A colorimetric receptor L was prepared. Receptor L can selectively sense F− based on distinct color changes among a series of ions. It can selectively sense F− through an intramolecular hydrogen bond interaction. A Job plot indicated a 1:1 complexation stoichiometry between receptor L and F−. The association constant for L–F− in CH3CN was determined as 9.70 × 104 M−1 using a Stern–Volmer plot.
