| 摘要: |
| 光动力治疗主要通过光敏剂在特定波长光源的激发下发生光动力学反应,产生单线态氧而发挥其破坏肿瘤细胞的作用.金属铱配合物,由于金属铱的重原子效应,在被合适的光激发后经过系间窜越到达三重态,把能量传递给氧分子从而产生单线态氧用于光动力治疗. |

| Abstract: |
| Photodynamic therapy can destruct tumor cells by singlet oxygen which is generated via a photodynamic reaction of the photosensitizer under a specfic excitation wavelength.Due to the heavy atom effect of metal iridium,iridiumcomplexes are excited by suitable light and then reach their excited triple state through intersystem crossing.The excited iridium complexes transfer energy to oxygen molecules to produce singlet oxygen for photodynamic therapy. |
| Key words: iridium complexes photodynamic therapy chemical therapy |
