    Abstract
    Chiral self-assembled organic nanoparticles with circularly polarized luminescence (CPL) properties can be utilized as a new kind of chiral luminescent materials for practical applications. However, no such chiral organic nanoparticles with full-color and white CPL properties have been reported so far. Herein, five pairs of self-assembled chiral nanoparticles based on optically stable helical aromatic amide enantiomers were conveniently obtained. The chiral nanoparticles showed about 200 nm uniform sphere, high fluorescence quantum yields, and large Stokes shifts. Especially, the chiral nanoparticles exhibited both obvious ...

    Chiral self-assembled organic nanoparticles with circularly polarized luminescence (CPL) properties can be utilized as a new kind of chiral luminescent materials for practical applications. However, no such chiral organic nanoparticles with full-color and white CPL properties have been reported so far. Herein, five pairs of self-assembled chiral nanoparticles based on optically stable helical aromatic amide enantiomers were conveniently obtained. The chiral nanoparticles showed about 200 nm uniform sphere, high fluorescence quantum yields, and large Stokes shifts. Especially, the chiral nanoparticles exhibited both obvious mirror-image circular dichroism signals and full-color CPL properties with luminescence dissymmetry factors of about 10–3, which were comparable to those of CPL-active quantum dots. Moreover, the chiral organic nanoparticles with white CPL could also be easily achieved using the three-primary-color enantiomers via intermolecular energy resonance transfer.
