Abstract
Current research work reports the ‘Click’ generation of a ligand, 1- naphtholphthalein linked 1,2,3-triazole (1-NPT) and its “turn-off” absorbance response on binding with Co(II) ions. Copper(I) catalyzed alkyne-azide cycloaddition reaction (CuAAC), a highly stereoselective reaction of ‘Click Chemistry’ is employed to synthesize the five membered heterocyclic ring based probe 1-NPT, that has been successfully characterized by spectroscopic techniques like IR, NMR (1H, 13C) and Mass spectroscopy. The chemosensing behavior of 1-NPT was analyzed by performing UV–Visible titrations with different metal ions like Mn(II), Hg(II), Cd(II), Pb(II), Cu(II), Fe(II), Zn(II), Ba(II), Cr(III), Co(II), K(I) and Na(I) in CH3CN:H2O (4:1, v/v) solution and the results obtained signify the selectivity of synthesized receptor towards Co(II) ions with minimum detection limit of 1.87 µM and 1:1 stoichiometry of 1-NPT:Co(II) complex with no interference of other metal ions.
