近离子对Ir（bdpSO 3）（cod）（IMes）]是一种有效的光敏剂，而溶剂分离的阴离子是高度荧光的。控制离子缔合支配激发能量的路径，激发能量被引导到S1状态（荧光）或经由系统间穿越进入T1状态（1O2生成）。NHC供体的调节影响光敏特性，并且只有富电子NHC提供高效的光敏剂。
The close ion-pair of Ir(bdpSO3)(cod)(IMes)] is an efficient photosensitizer, while the solvent-separated anion is highly fluorescent. Controlling ion association governs the path of the excitation energy which is channeled either to the S1 state (fluorescence) or via intersystem crossing into the T1 state (1O2 generation). Modulation of NHC donation affects the photosensitizing properties and only electron-rich NHC provide highly efficient photosensitizers.
