Abstract
We have developed a FRET-based ratiometric fluorescent probe for the detection of CNâ using a fluorescein-Zn-naphthalene ensemble (NFH·Zn2+). The sensing mechanism was ascribed by displacement approach. The chemosensor exhibits high selectivity and sensibility for CNâ. The speculation was supported by fluorescence emission spectra, UV-vis spectrum, 1H NMR titration experiments, and mass spectra. The interconversion of probe NFH and NFH·Zn2+ via the complexation/decomplexation by the modulation of Zn2+/CNâ mimics INHIBIT gate. In addition, it also shows an excellent performance in 'dip stick' method.
