A Schiff-based colorimetric fluorescent sensor with the potential for detection of fluoride ions



A Schiff-based colorimetric fluorescent sensor with the potential for detection of fluoride ions



Journal of Fluorescence 23(6): 1107-1111



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 CH3CN was determined as 1.32*10(5) M(-2) by a Hill plot.
