Abstract Organelle‐targeted photosensitizers have been reported to be effective photodynamic therapy (PDT) agents. In this work, we designed and synthesized two iridium(III) complexes that specifically stain the mitochondria lysosomes of living cells, respectively. Both exhibited long‐lived phosphorescence, which is sensitive oxygen quenching. The photocytotoxicity was evaluated under normoxic hypoxic conditions. results showed HeLa cells treated with mitochondria‐targeted complex maintained...
