||Exploiting the mechanism by which charge moves throughout a complex is an attractive area of research to scientists looking for renewable forms of energy. An example of an electron transfer mechanism is Proton Coupled Electron Transfer (PCET). PCET is broken into the following classes: PT-ET: proton transfer, followed by electron transfer; ET-PT: electron transfer, followed by proton transfer; and EPT: simultaneous movement of an electron and proton. [Ru(bpy) 2 (bpy(OH) 2 )][PF 6 ] 2 (bpy= 2,2'-bipyridine; bpy(OH) 2 = 4,4'-dihydroxy-2,2'-bipyridine) was synthesized and its electronic properties were studied as a function of protonation state of the hydroxyl groups. The complex was synthesized by reaction of Ru(bpy) 2 Cl 2 with bpy(OH) 2 and studied with the use of UV-Vis and luminescence spectroscopies in addition to cyclic voltammetry. Bases of different pK a values and solvents of varying polarities were used in the experiments to help determine the effects of the bpy(OH) 2 protons on the electronic transitions of the complex. The properties of the target complex were compared to [Ru(bpy) 3 ][PF 6 ] 2 and [Ru(bpy) 2 (bpy(OCH 3 ) 2 )][PF 6 ] 2 ((bpy(OCH 3 ) 2 = 4,4'-dimethoxy-2,2'-bipyridine) in a systematic study.
