Abstract

A simple Schiff-based colorimetric fluorescent receptor 1 was prepared. It exhibits a "turn-on-type" mode with high sensitivity in the presence of F^-. The change in color is very easily observed by the naked eye in the presence of F^-, whereas other anions do not induce such a change. Job plot indicated a 1:2 complexation stoichiometry between receptor 1 and F^-. The association constant for 1-F^- in CH ₃CN was determined as 1.32*10⁵ M^-2 by a Hill plot.
