Compared with other fluorescent probes, ratiometric fluorescence responses are more attractive because the ratio between the two emission intensities can be used to measure the analyte concentration and provide a built-in correction for environmental effects. A highly selective and sensitive ratiometric fluorescent probe for Fe3+ was synthesized, which exhibits an enhanced fluorescence with a large red-shift in emission from 361 to 455Â nm upon addition of Fe3+. The red-shift of the emission peak can be ascribed to the reformed orbital, and the increase of emission intensity may be ascribed to the inhibition of the rotation of C-C bonds between each two aromatic rings.
