Solution‐Processed White Circularly Polarized Organic Light‐Emitting Diodes Based on Chiral Binaphthyl Emitters
Bibliographic record
Abstract
Abstract By combining the blue and orange CPL or functionalized bis‐benzoxanethones emitters ( S ‐/ R ‐ BN‐tCz and S ‐/ R ‐ BN‐PXZ ), warm white CP‐OLEDs were fabricated using solution‐processed single emitting layer strategy. The successful realization of white CP‐EL benefited from the same stable binaphthyl chirality and similar rigid structure of the two emissive CPL emitters. The devices exhibited the low turn‐on voltage of ≈4.3 V, maximum luminance of ≈10200 cd m −2 and maximum current efficiency of ≈2.0 cd A −1 . Most significantly, the devices with CIE coordinates of (0.32, 0.45) displayed intense CP‐EL signals in the spectral range of 450 to 650 nm, and showed stable g EL values of ≈10 −3 as the luminance increased from 100 to 6000 cd m −2 . To the best of our knowledge, this work provides for the first time a simple and feasible strategy to fabricate solution‐processed white CP‐OLEDs based on the co‐doping of the CPL emitters.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
