[Ru(4,4-dichloro-2,2-bipy)3]Cl2 complex has been synthesized and purified by column chromatography resulting in a 60% yield. The complex was characterized by NMR, IR, and UV-Vis. Electrochemistry data confirmed the redox potential of Ru2+/Ru3+ in the [Ru(4,4-dichloro-2,2-bipy)3] Cl2 complex was lower than the standard [Ru(bpy)3](BF4)2 in dimethyl sulfoxide. 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 its photosensitizing properties by adding auxiliary ligands to the chlorinated bipyridine groups.
