Abstract
Two unique fluorene monomers (PTE and MTE) and polyfluorene-based homopolymers (PPTE and PMTE) containing covalently linked aromatic ether (AE) moieties were synthesized via microwave Ni(0)-mediated Yamamoto coupling reactions. The monomers and polymers demonstrated thermal stabilities, as determined by TGA, much higher than status quo poly(9,9′-dioctylfluorene) (PFO) (i.e., greater than 100 °C), and most importantly, the spectral emission remained stable after annealing in ambient and inert atmospheres. PPTE and PMTE were annealed in an N 2 atmosphere at 200 °C for 72 h and at 150 °C in ambient atmosphere for 1 h showing no evidence of green emission, in stark contrast to PFO. The results show that PFs with AE moieties present in the 9-position exhibit stable blue emission.

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
