Preferred-handed propeller conformation was induced by circularly polarized light irradiation to three amorphous molecules with trigonal symmetry, and the molecules with induced chirality efficiently exhibited blue circularly polarized luminescence. In both chirality induction and luminescence, chirality appeared to be amplified due to intermolecular interactions through π-stacking.
