title: A colorimetric sensor for the selective detection of fluoride ions.
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 × 104M-1using a Stern-Volmer plot.
