Abstract:A fluorescent sensor for Fe3+, 2-[3'.6'-bis(ethylamino)-2',7'-dimethyl-3-oxospiro[1H-isoindole-1,9'-[9H] xanthen]-2-((2-aminoethyl)methyl)]phenol, has been synthesized and characterized by H-1 NMR, C-13 NMR and X-ray crystallography. The photophysical processes of the Fe3+-sensor have been carefully investigated by fluorescence and absorbance spectra. Upon addition of Fe3+, the sensor shows strong fluorescence change with absorbance and emission peaks at 530 and 554 nm, respectively. Other metal ions have no such response. (C) 2009 Elsevier B.V.
