The photophysical properties of Ir(III) corroles differ from those of phosphorescent porphyrin complexes, cyclometalated and polyimine Ir(III) compounds, and other luminescent metallocorroles. Ir(III) corrole phosphorescence is observed at ambient temperature at wavelengths much longer (>800 nm) than those of most Ir(III) phosphors. The solvatochromic behavior of Ir(III)-corrole Soret and Q absorption bands suggests that the lowest singlet excited states (S(2) and S(1)) are substantially more polar than the ground state.
金属卟啉配合物的光物理性质不同于磷光卟啉配合物、环金属化和聚亚胺铱(III)化合物以及其他发光金属卟啉。在环境温度下，可以观察到 Ir(III) 卟啉磷光，其波长比大多数 Ir(III) 荧光粉长得多(>800nm)。Ir(III)-卟啉 Soret 和 Q 吸收带的溶剂化变色行为表明，最低的单重激发态(S(2)和 S(1))比基态具有更大的极性。
