In a system where DMF:H2O=1:1 (V / V), the probe molecule is excited by using 320nm light, and emission occurs at 461nm. When cyanide ion is added, intra-molecular charge transfer (ICT) process is broken, emission peak at 461nm is reduced, and new emission peak occurs at 425nm. Therefore, solution fluorescence is turned from bluish green to deep blue. In a system wherein cyanide ion coexists with other anions, the probe molecule shows high interference resistance, high specificity, and high sensitivity.
