Abstract
We report the synthesis and characterization of three new poly(2,7-carbazole) derivatives, namely, poly[ N -9-heptadecanyl-2,7-carbazole- alt -5,7-di(3-octylthien-2-yl)-2,3-di(thien-3-yl)-thieno[3,4-b]pyrazine (P1), poly[ N -9-heptadecanyl-2,7-carbazole- alt -5,7-di(3-octylthien-2-yl)-2,3-di(phen-1-yl)-thieno[3,4-b]pyrazine (P2), and poly[ N -9-heptadecanyl-2,7-carbazole- alt -5,7-di(3-octylthien-2-yl)-2,3-di(4-octylphen-1-yl)-thieno[3,4-b]pyrazine (P3), which reflect green light in their neutral state and show transmissive brown when oxidized. These two colors are compatible for adaptive camouflage for military assets. All solid-state electrochromic cells were prepared using spray-coated films of electrochromic conjugated polymer (P1−P3) as active layer. We report the development of multicolored electrochromic cells (MEC) based on the additive color mixing theory. MEC of various sizes were prepared from 2.5 × 2.5 cm, and up to 12.5 × 12.5 cm. Finally, we also describe the fabrication of a multicolored electrochromic cell with an active surface of 156 cm 2 .

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
