    The thiosemicarbazone MA (N'-(anthracen-9-ylmethylene) morpholine-4-carbothiohydrazide) was synthesised and characterised for selective cyanide ion sensing. The interaction between cyanide ion and sensor MA was examined thoroughly with the aid of absorption, emission and NMR spectra, and the binding constant was estimated both in organic as well as aqueous media. The detection limit obtained was much lower compared to those reported recently. NMR spectra titration studies clearly indicated that deprotonation occurs from the N-H group of the receptor. The sensing mechanism was further understood by DFT and TDDFT methodologies using Gaussian software. Insilco investigation reveals that the added cyanide ion caught the proton from the N-H group, which support the experimental results. The synthesised ligand MA found to be a very good candidate for selective sensing of cyanide.
