二甲基甲酰胺中的[Ru(bpy) 3](SCN) 2 发生光解，量子产率为10-3或更低，具体取决于硫氰酸盐浓度。两种主要的光产物，[Ru (bpy) 2 (DMF)(NCS)]+ 和 [Ru (bpy) 2 (NCS) 2]，分别通过 SCN~ 独立（显然）和 SCN~ 依赖途径产生。考虑二次光解和离子对/离子三重态（两个主要光解步骤）模型。基于量子产率对硫氰酸盐浓度的详细依赖性，后者似乎更合理。
[Ru (bpy) 3](SCN) 2 in dimethylformamide is photolyzed with a quantum yield of 10-3 or less depending on thiocyanate concentration. The two main photoproducts,[Ru (bpy) 2 (DMF)(NCS)]+ and [Ru (bpy) 2 (NCS) 2], are produced via SCN~-independent (apparently) and SCN~-dependent pathways, respectively. A secondary photolysis and an ion-pair/ion-triplet (two primary photolytic steps) model are considered. The latter appears somewhat more reasonable, on the basis of the detailed dependence of the quantum yields on the thiocyanate concentration.
