An efficient colorimetric and fluorescent chemodosimeter for Fe3+ ions has been developed. The visual and fluorescent behaviors of the receptor toward variousmetal ions were investigated. The receptor shows exclusive response toward Fe3+ ions and also distinguishes Fe3+ from other cations by color change and unusual fluorescence enhancement in aqueous solution (DMSO/H2O = 4/1, v/v). Thus, the receptor can be used as a colorimetric and fluorescent sensor for the determination of Fe3+ ion. The visual color detection limit and the fluorescence detection limit of the receptor towards Fe3+ are (1.42 +/- 0.01) x 10(-6) Mand (7.57 +/- 0.04) x 10(-8) M, respectively. The fluorescence microscopy experiments showed that the receptor is efficient for detection of Fe3+ in vitro, developing a good image of the biological organelles. The sensing mechanism is proven to be a hydrolysis process.
