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 CH 3 CN was determined as 9.70 × 10 4 M −1 using a Stern–Volmer plot.
