Naphthalimide fluorescence
Witryna1 gru 2010 · The secondary amine linked naphthalimide–coumarin (NC) 3 conjugate shows significant red shift in absorption and fluorescence, whereas other NCs show moderate red shifts. Among NCs conjugates, only thioether linked NC 2 clearly showed a significant AIE effect while the other NCs conjugates showed aggregation caused … Witryna14 kwi 2024 · The fluorescence lifetime of Lyso-V and protonated Lyso-V exhibited satisfactory viscosity-sensitive properties, and the lifetime increased from 0.30 to 4.62 ns with the increase of viscosity from 0.6 to 359.6 cP (Figure 8A). In addition, the lifetimes of neutral and protonated Lyso-V are identical with the increase of viscosity (Figure 8A).
