Design of a dual sensing highly selective cyanide chemodosimeter based on pyridinium ring chemistry

Author affiliations

Abstract

A new chemodosimeter, Quino-P, recognizes the strongly nucleophilic cyanide by dual colorimetric and fluorescence ‘off–on’ signalling responses. Noteworthily, several other anions, even in significantly higher concentrations, induce no detectable photophysical perturbations. The chemodosimeter mechanism involves formation of a C4–cyano adduct, which exhibits an uncommon phenomenon of enhanced internal charge transfer interaction.
