Synthesis and Characterization of tris(4,4-dichloro-2,2-bipyridine) Ruthenium (II)

A new ruthenium (II) [Ru(4,4-dichloro-2,2-bipy)3] Cl2 complex has been synthesized using a new procedural method. The complex was characterized by NMR, IR, and UV-Vis. After purification through column chromatography with alumina, the percent yield was 60.39%. Electrochemistry data confirmed the presence of Ruthenium- bipyridine bonds, very similar to electrochemical data of [Ru(bpy)3]Cl2. The quantum yield of the [Ru(4,4-dichloro-2,2-bipy)3] Cl2 complex was calculated after comparing with calibrated standards. This complex will be used to improve the photosensitizingproperties of the complex by adding auxiliary ligands to the chlorinated bipyridine group.
