a Normalized absorbance of DPBF (50 μM) at 411 nm in the presence of compound 1 (10 μM) or 4 (10 μM) as a function of irradiation time (white light: 20 mW/cm2). b–d Degradation of NBT (24 μM) by O2−• under different treatments (“+” represents with irradiation, “−” represents without irradiation, white light 20 mW/cm2, 3 min). e Schematic illustration of O2−• and 1O2 generation. Abs. Absorb, Fl fluorescence, ISC Intersystem Crossing, S0 ground state, S1 singlet state, T1 triplet state.
