Of these probes, the pyrene conjugate <jats:bold>2<\/jats:bold> acts as a dual colorimetric and fluorescent chemodosimeter for the selective and sensitive detection of cyanide ions. The detection limit of probe\u2005<jats:bold>2<\/jats:bold> for CN<jats:sup>\u2212<\/jats:sup> ions was found to be 10\u2005ppb (30\u2005n<jats:sc>M<\/jats:sc>). The nature of interaction has been thoroughly studied through various techniques such as <jats:sup>1<\/jats:sup>H\u2005NMR and IR spectroscopy, HRMS, and isothermal calorimetric (ITC) studies. These studies confirm that probe\u2005<jats:bold>2<\/jats:bold> forms a 1,2\u2010adduct in the presence of CN<jats:sup>\u2212<\/jats:sup> ions.
