<p>Aggregation-induced emission active chiral polymer dots (AIE@CPdots) are considered as a sort of high-performance emission layer (EML) of circularly polarized organic light-emitting diodes (CP-OLEDs) since they exhibit persistent emission stability, high photoluminescence quantum yields, excellent solution processability, facile functionalization, tunable bandgap-governed emission, and better device processability. So far, in this regard, such cases have rarely been reported. In this study, a pair of chiral conjugated polymer enantiomers (<i>R</i>/<i>S</i>-PFC) was synthesized by using three monomers of chiral binaphthalene moiety, fluorenyl linker, and AIE-active cyanostyrene dye under the Suzuki polymerization reaction. After annealing at 110 °C, the resulting <i>R</i>/<i>S</i>-PFC can self-assemble as chiral nanoparticle AIE@CPdots at the mixed solvent of chloroform and <i>n</i>-hexane mixed in a volume ratio of 9:1 and show the enhanced circularly polarized luminescence emission (luminescence dissymmetry factor (∣<i>g</i>_lum∣) = 4.4 × 10⁻³ at 462 nm). Interestingly, AIE@CPdots can serve as the EML of CP-OLEDs, achieving high-performance circularly polarized electroluminescence (electroluminescence dissymmetry factor (∣<i>g</i>_EL∣) = 3.0 × 10⁻³ at 464 nm, maximum luminance (<i>L</i>_max) = 6022 cd m⁻², maximum current efficiency (CE_max) = 1.10 cd A⁻¹). This research provides a new idea for designing excellent EML materials of CP-OLEDs promoted by chiral self-assembled AIE@CPdots.</p>
