Fig. 11. (a) Molecular structures of TPy, TPPy, TTPy, MeOTTPy, and TPE-TTPy. (b) Plots of fluorescence intensities of AIEgens versus dye concentrations in PBS solution. Inset: Corresponding statistical histogram of the critical aggregation concentrations (CAC) of AIEgens. (c) ROS generation of TTPy (1 μM) upon white light irradiation using dichlorofluorescin (DCFH) as an indicator, where I₀ and I are fluorescence intensities of DCFH before and after light irradiation. (d) Colony-forming unit (CFU) reduction of E. coli and S. aureus with/without TTPy (2 μM) and white light (60 mW cm⁻²) treatment. (e) Photographs of S. aureus-infected wounds after treatment with TTPy with/without white light irradiation (60 mW cm⁻²) on day 1 and day 4 post-infection. (f) Statistical histogram of bacterial colonies on the agar plates originating from the infected sites on rats with different treatments. Reproduced from ref. 75 with permission.
