dc.description.abstractTwo new mixed ligand cobalt(III) complexes containing bibenzimidazole (bbenzimH<sub>2</sub>) ligand with composition [Co(phen)<sub>2</sub>bbenzimH<sub>2</sub>](ClO<sub>4</sub>)<sub>3</sub> (1) and [Co(bpy)<sub>2</sub>bbenzimH<sub>2</sub>](ClO<sub>4</sub>)<sub>3</sub> (2) have been synthesized and characterized using UV–Vis, Infrared, ESI-MS and cyclic voltammetric techniques. Both complexes 1 and 2 exhibited quasi-reversible electrochemical wave. The anion binding studies with these metallo-receptor complexes were carried out using UV–Vis and fluorescence spectroscopic titrations and complex 2 was found to be selective towards iodide anion. Though complex 2 possesses potential hydrogen bonding sites, namely –NH, it was found that the basic anions like F-, OH- and OAc- do not bring about any dramatic visual colorimetric changes. However, metallo-receptor 2 brings about vivid color change with iodide anion visually and this could be due to charge transfer transition via ion pair formation with iodide ion
