    A new optical chemosensor N1 was designed and synthesized by condensing 4-chloro-7-nitrobenzofurazan with 2-aminophenylbenzimidazole. In CH3OH : H2O (1 : 1, v/v) medium, sensor N1 exhibited high selectivity and sensitivity towards Cu2+ and Hg2+ ions by showing a distinct colour change from pale yellow
