Iridium(III) complexes are emerging as a promising tool in the area of detection and therapy due to their prominent photophysical properties, including higher photostability, tunable phosphorescence emission, long-lasting phosphorescence, and high quantum yields. In recent years, much effort has been devoted to develop novel near-infrared (NIR) iridium(III) complexes to improve signal-to-noise ratio and enhance tissue penetration. In this review, we summarize different classes of organometallic NIR iridium(III) complexes for detection and therapy, including cyclometalated ligand-enabled NIR iridium(III) complexes and NIR-dye-conjugated iridium(III) complexes. Moreover, the prospects and challenges for organometallic NIR iridium(III) complexes for targeted detection and therapy are discussed.
金属铱(III)配合物由于其突出的光物理性质,如更高的光稳定性、可调磷光发射、长磷光寿命和高量子产率,在检测和治疗领域作为一种很有前途的工具而出现。近年来,人们致力于开发新型近红外(NIR)金属铱(III)配合物,以提高信噪比并增强组织穿透性。在这篇综述中,我们总结了用于检测和治疗的不同类型的有机金属近红外铱(III)配合物,包括环金属化配体增强的近红外铱(III)配合物和近红外染料偶联的铱(III)配合物。此外,还讨论了有机金属近红外铱(III)配合物在靶向检测和治疗方面的前景和挑战。
