A BODIPY Derivative for Selective Fluorescent Chemosensing of Iron (III)

Abstract

A BODIPY derivative functionalized with a phenyl group at the meso-position was synthesized and characterized through 1H NMR and UV–Vis absorption/emission spectroscopies. The compound showed an absorption band at 497 nm and a fluorescence band at 513 nm, with a ΦF = 0.68 in acetonitrile. The evaluation of the chemosensing ability of the BODIPY was investigated in the presence of several ions with environmental and biomedical relevance. A highly selective fluorimetric response was observed for Fe3+ through fluorescence quenching upon successive additions of this cation.
