Oligofluorene-based electrophoretic nanoparticles in aqueous medium as a donor scaffold for fluorescence resonance energy transfer and white-light emission

Self-assembled, surfactant-free organic nanoparticles of an oligofluorene derivative with high colloidal stability were prepared in aqueous medium. The blue emission of the nanoparticles was tuned to white through fluorescence resonance energy transfer (FRET) by encapsulating an orange-red emitting dye (1 mol%) within the nanoparticle scaffold.
