A novel fluorophore,N-(2-hydroxy-1-naphtalamido)-N'-phenyl-thiourea was synthesized and the structure were characterized by IR,~1H NMR and ESI-MS.It showed fluorescence in acetonitrile in the presence of some transition metal ions,the highest sensitivity was observed with Hg~(2+).It was also found that the receptor 1 show sensitive and selective response toward Hg~(2+) in water-acetonitrile(50/50,v/v).Preliminary investigations were carried out to understand the selective signaling mechanism for Hg~(2+),which was shown to form a 2:1 complex with the ligand.
