Triplet photosensitizers have attracted much attention due to the applications for singlet oxygen production,such as photodynamic therapy (PTD),[1] photocatalysis,[2]and triplet-triplet annihilation (TTA) upconversions,etc.3 However,conventional photosensitizers are usually limited to the phosphorescent transition metal complexes.
