A Selective, Colorimetric, and Fluorescent Chemodosimeter for Relay Recognition of Fluoride and Cyanide Anions Based on 1,1′-Binaphthyl Scaffold

Abstract

The reaction-based relay recognition of fluoride and cyanide anions was demonstrated for the first time, with rapid response and unique triple (fluorescence color, intensity and absorption band) output modes in either of two sequential sensing events. Ratiometric determination of these two anions by fluorescence and/or absorbance spectra is also achieved.
