Chromo-Fluorogenic Detection of Cyanide Ion with a Cyanine Probe

“…In our previous work, we reported the synthesis and photophysical characterization of sulfo-cyanine 1 (Figure 1), as well as its evaluation as an efficient colorimetric probe for cations, especially for Cu 2+ and Fe 3+ [10,11]. Here, we study the sensing ability of this compound for different anions with environmental and medicinal relevance.…”

“…Following our previous work focused on the synthesis of a sulfo-cyanine dye and its evaluation as an optical chemosensor for cations [10,11], we now report its chromofluorogenic ability for anion detection in acetonitrile solution. Therefore, the interaction of this compound with several anions was evaluated via preliminary chemosensing studies, followed by UV/Vis, fluorescence and NMR titrations.…”
