Triplet photosensitizers are crucial for photodynamic therapy(PDT),photocatalysis,and triplet-tripletannihilation(TTA) upconversion.[1] Phosphorescent transition metal complexes,such as Ru(bpy)3Cl2(bpy =2,2-bipyridine) were used as triplet photosensitizers.However,the conventional transition metal complexesusually show weak absorption of visible light.For example,the molecular absorption coefficients of Ru(bpy)3at 450 nm is less than 15000 M-1 cm-1.
