在许多充气溶剂体系中，[Ru(bpy)2Cl2] 在紫外线照射下可通过溶剂引发的自由基链反应在至少一些溶剂中氧化为 [Ru(bpy)2Cl2]+。在某些相同溶剂中，用蓝色或紫外线照射 [Ru(bpy)2Cl2]+ 会导致 Ru(II) 络合物发生光还原。在一些溶剂系统中，光稳定混合物是紫外线照射的最终结果。在其他情况下，受辐照的溶液要么完全是 Ru(II)，要么完全是 Ru(III)，具体取决于温度。极端温度敏感性被认为取决于氧气浓度。
In a number of aerated solvent systems, [Ru(bpy)2Cl2] can be oxidized to [Ru(bpy)2Cl2]+under UV irradiation, in at least some of these solvents by a solvent-initiated radical chain reaction. Irradiation of [Ru(bpy)2Cl2]+in the blue or ultraviolet in some of the same solvents caused photoreduction to the Ru(II) complex. In some solvent systems a photostationary mixture was the end result of UV irradiation. In others the irradiated solution was either completely Ru(II) or completely Ru(III), depending on the temperature. The extreme temperature sensitivity is thought to depend on the oxygen concentration.
