Abstract
Abstract It is well‐known that high‐performance circularly polarized organic light‐emitting diodes (CP‐OLEDs) remain a formidable challenge to the future application of circularly polarized luminescent (CPL)‐active materials. Herein, the design of a pair of AIE‐active chiral enantiomers ( L/D ‐HP) is described to construct chiral co‐assemblies with an achiral naphthalimide dye (NTi). The resulting co‐assemblies emit an inverted CPL signal compared with that from the L/D ‐HP enantiomers. After thermal annealing at 120 °C, the inverted CPL signal of this kind of L/D ‐HP‐NTi with a 1:1 molar ratio shows regular and ordered helical nanofibers arranged through intermolecularly ordered layered packing and is accompanied with a further amplified effect (| g em | = 0.032, λ em = 535 nm). Significantly, non‐doped CP‐OLEDs based on a device emitting layer (EML) of L/D ‐HP‐NTi exhibits a low turn‐on voltage ( V on ) of 4.7 V, a high maximum brightness ( L max ) of 2001 cd m −2 , and moderate maximum external quantum efficiency ( EQE max ) of 2.3%, as well as excellent circularly polarized electroluminescence (CP‐EL) (| g EL | = 0.023, λ em = 533 nm).

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
