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 CH3 CN was determined as 9.70×104 M-1 using a Stern-Volmer plot.
