Abstract

Abstract: A novel fluorescent sensor 4-(1H-Benzimidazol-2-yl)-2-methoxy-phenol derivative was synthesized. Solution of 4-(1H-Benzimidazol-2-yl)-2-methoxy-phenol (1 x 10^-7M) in DMSO displays highly sensitives and rapid respons to CN^- ion (values of LOD = 1.8 x 10^-6M and K_a= 2.5(± 0.26) x 10⁶ M^-1). Sensor 4-(1H-Benzimidazol-2-yl)-2-methoxy-phenol coordinated with CN^- ion form with a 1:1 binding stoichiometry.

Keywords: Fluorescent sensor, CN^- ion, Benzimidazole.
