Abstract

This work reports a simple strategy that induces and amplifies the luminescence dissymmetry factor (g_lum) of chiral thermally activated delayed fluorescence emitters by co-assembly with liquid crystals. Large g_lum values of +7.26 × 10⁻² and −5.45 × 10⁻² were obtained for FAC-PDMLM and PXZ-PDMLM, respectively.
