The dithiomaltolato complex [Ru(bpy2)ttma]+ has previously been shown to produce unusual C-H activation products upon outer-sphere oxidation. Photolysis of [Ru(bpy2)ttma]+ in presence of  MV+2, Ru+3, Co+3, or DDQ quenchers forms similar products. But this reactivity is engendered only upon excitation into an absorbance band attributed to the ttma ligand. For comparison, the photolysis of Zn(ttma)2 under the same conditions induces long lived transient absorbance changes that suggest electron ejection from a non-emissive photostate.
