A new ratiometric fluorescent probe was designed based on hemicyanine moiety as a cyanide reaction site for nucleophilic addition. The titration experiment for CN- showed this probe exhibits high selectivity, a low limit of detection to 20 nM and quick response for CN- sensing. At the addition of CN...
