Advances in iridium complexes for bioimaging and cancer therapy

Iridium complexes are widely used in the fields of optical materials, biosensing, bioimaging, and photodynamic therapy due to their excellent properties such as easy structural modification, high luminescence efficiency, and long luminescence lifetime. The photophysical and photochemical properties of iridium complexes are affected by ligands, and the optical properties of iridium complexes can be regulated by ligands to improve biological imaging. Besides, iridium complexes can also have the ability to target specific organelles and affect their functions through ligand regulation, thus showing unique antitumor activity which is expected to replace platinum-based anticancer drugs, identifying a research hotspot of metal complexes in anticancer drugs. Outlines the advances in iridium complexes for targeted organelle bioimaging, improving photodynamic therapy efficacy, and acting as anticancer drugs in recent years, hopefully facilitating the application of iridium complexes in the biomedical field.
