Abstract

fetched live from OpenAlex

Conjugated fluorene- alt -pyridine and fluorene- alt -thiophene polymers containing phosphorescent iridium complexes have been synthesized. Exchanging the 2,5-linked pyridine group with the 3,4-linked thiophene group resulted in a blue shift in the absorption and emission spectra of the conjugated polymers. Upon incorporation of the thienyl unit, phosphorescent quantum yields of films increased from 0.05 to 0.20 and electrophosphorescent external quantum efficiencies increased from 0.32 to 0.84%. These results are attributed to raising the triplet energy of the main chain polymer, with respect to the Ir phosphor, thereby reducing quenching of the phosphor by the main chain.

Full frame distilled prediction

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.
