• • The synthesized chiral polymer enantiomers R/S-PFC, after annealing at 110 °C and self-assembly in chloroform/n-hexane (9:1 v/v), yield AIE@CPdots with a luminescence dissymmetry factor |g_lum| = 4.4 × 10⁻³ at 462 nm, demonstrating effective chiral transfer and amplified CPL, which is critical for achieving high dissymmetry in solution-processed OLEDs.
• • CP-OLEDs employing AIE@CPdots as the emission layer achieve an electroluminescence dissymmetry factor |g_EL| = 3.0 × 10⁻³ at 464 nm, a maximum luminance of 6022 cd m⁻², and a maximum current efficiency of 1.10 cd A⁻¹, indicating that self-assembled chiral dots can simultaneously provide decent circular polarization and practical brightness for display applications.
• • The use of AIE-active cyanostyrene dye within the polymer backbone ensures aggregation-induced emission, which mitigates concentration quenching and maintains high photoluminescence quantum yields in the solid state, a key requirement for efficient OLED emissive layers.
• • The self-assembly approach via solvent mixing and thermal annealing offers a scalable, low-cost route to fabricate chiral emissive nanomaterials, overcoming the low chiral transfer efficiency often seen in inorganic nanoparticle systems, and thus provides a viable pathway for industrial production of CP-OLEDs.
