- This report demonstrates that changing the position of the carbon–metal bond in a polypyridyl cyclopalladated complex, i.e. going from PdL¹ (N^N^C^N) to PdL² (N^N^N^C), dramatically influences the photodynamic properties of the complex in cancer cells. This effect is primarily attributed to the significantly difference in absorbance and singlet oxygen quantum yields between the two isomers.
