| Abstract: | Cyclometalated Ru(II) complexes having a 3-phenylbenzob]1,6]naphthyridine (phbn) ligand have been synthesized and characterized by spectroscopic methods. The photo- and electrochemical redox behavior of the complexes are demonstrated. Complex Ru(phbn)(bpy)(2)]PF(6) (1]PF(6)) readily undergoes proton coupled two electron reduction by chemical, electrochemical, and photochemical methods to generate Ru(phbnHH)(bpy)(2)]PF(6) (1HH]PF(6)). The photochemical oxidation of 1HH]PF(6) was also observed in presence of p-chloranil. |
