Abstract

Abstract A simple quinoline derived probe 3 has been described. Probe 3 having aldehyde function upon interaction with cyanide undergo nucleophilic addition reaction to form cyanohydrin derivative 4 in which fluorescence intensity enhances significantly,'turn-on'by photoinduced electron transfer (PET) OFF–ON mechanism. The color of probe solution switched-on to fluorescent blue which is visible to the naked-eye. Job's plot analysis ...
