| Abstract: | 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. |
