发蓝光配合物：铱配合物表现出双磷光。室温下的蓝色磷光，归因于T - ILCT→T - LLCT转换，通过高能量势垒（~ 6.9 kcal mol-1）发生，这是由大振幅运动引起的，例如螯合基团的部分扭曲，从而翻转轨道构型，从而导致双磷光。
Blue-emitting complexes: Iridium complexes exhibit dual phosphorescence. The blue phosphorescence at room temperature, attributed to T ILCT→ T LLCT conversion, occurs via a high energy barrier (∼ 6.9 kcal mol-1) resuiting from large-amplitude motions, such as partial twisting of the chelate groups which flip the orbital configuration and consequently results in dual phosphorescence.
