Abstract

fetched live from OpenAlex

Abstract Two chiral binaphthyl polymers ( R / S ‐P1 and R / S ‐P2 ) with different dihedral angles of the binaphthyl moiety were chosen as chiral inducers to construct chiral co‐assemblies with an achiral pyrene‐naphthalimide dye ( NPy ) and then acted as the emitting layer (EML) of circularly polarized electroluminescence (CP‐EL) devices. The anchored dihedral angle of R / S ‐P2 not only exhibited the enhanced chirality signal, but also had a strong chirality‐inducing effect on the achiral NPy dye in the chiral co‐assembly ( R / S ‐P2) 0.6 ‐(NPy) 0.4 . After annealing at 120 °C, the CPL signal (| g em |) of ordered helical nano‐fibers ( R / S ‐P2) 0.6 ‐(NPy) 0.4 was amplified to 5.6×10 −2 , which was about 6‐fold larger than that of ( R / S ‐P1) 0.6 ‐(NPy) 0.4 . The amplified g em value of ( R / S ‐P2) 0.6 ‐(NPy) 0.4 was due to the formation of a helical co‐assembly through the strong π–π stacking interaction between the R / S ‐P2 and the achiral NPy . This kind of ordered helical nano‐fibers ( R / S ‐P2) 0.6 ‐(NPy) 0.4 acted as the EML of CP‐OLEDs, and achieved an excellent CP‐EL performance (| g EL |=4.8×10 −2 ).

Teacher imitation

Not 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.
