Abstract
ABSTRACT Circularly polarized luminescent materials find extensive applications in 3D displays, information encryption, and photoinduced supramolecular chirality. However, controlling the handedness of circularly polarized luminescence remains a significant challenge in advancing optical technologies. In this study, we present a Janus circularly polarized light emitter comprising a fluorescent film combined with chiral nematic cellulose with switchable chirality. The emitter achieves maximum luminescence dissymmetry factors (0.28 and −0.65) through mode switching. In addition, we show the emitter's versatility in inducing chiral helices in azobenzene polymers with varying polar groups, resulting in significant chiral signals. Importantly, the chirality of these polymers can be switched by altering the luminescence mode of the emitter. These results are expected to facilitate the efficient design of chiral luminescent materials and photoinduction devices.

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
