Hydrogen Bond Acceptors and Additional Cationic Charges in Methylene Blue Derivatives: Photophysics and Antimicrobial Efficiency
Figure 5
Time- and spectrally resolved singlet oxygen luminescence. Time- and spectrally resolved singlet oxygen luminescence of methylene blue and exemplarily its derivative MB-4 in air saturated H2O at 25°C; singlet oxygen is generated and detected at 1275 nm with a decay time of ≈3.5 μs with all derivatives (see supporting information).
