Witryna15 gru 2014 · Naphthalimide derivatives, which are widely used as fluorescent dyes, have excellent photophysical properties, such as high fluorescence quantum yields, large Stokes shifts, strong absorption band and stability. WitrynaAbstract Novel naphthalimide derivatives (NIM) with donor–acceptor architecture were successfully constructed and their unique fluorescent properties were investigated. In particular, the fluorescence intensities of 4-methoxystyrene substituted NIM-1 were solvent independent and its quantum yields varied from 0.4 in toluene to 0.52 in MeOH.
