A new fluorescent chemosensor derived from sugar-thiacrown-ether appended calix[4]arene, coupled with pyrene units was designed and synthesized. Upon the addition of Fe2+, or Fe3+, changes were observed in both the fluorescence and absorption spectra. The fluorescence intensities are significantly quenched indicating high selectivity for these two metal ions over other transition metals investigated.
