A New Schiff Base Chemodosimeter: Selective Colorimetric and Fluorescent Detection of Fe (III) Ion.

A new efficient chemosensor 1 was prepared, for the detection of Fe(3+) in solutions as a colorimetric and fluorescent sensor. The visual and fluorescent behaviors of the receptor toward various metal ions were also explored. The receptor shows exclusive response toward Fe(3+) ions and also distinguishes Fe(3+) from other cations by color change and fluorescence enhancement in hydroalcoholic solution (MeOH/H2O = 9/1, v/v). Thus, the receptor can be used as a colorometric and fluorescent sensor for the determination of Fe(3+) ion. The fluorescence microscopy experiments showed that the chemosensor is efficient for detection of Fe(3+) in vitro, developing a good image of the biological organelles. Graphical Abstract ᅟ.
