Abstract
2,7-Dibromoazadibenzocyclooctyne (DIBAC-Br 2 ) was prepared as a pro-monomer unit that could be modified by the metal-free strain-promoted azide–alkyne cycloaddition (SPAAC). Click cyclization of DIBAC-Br 2 with five different benzyl azides produced a homologous series of monomers with different functionality on the resulting triazole ring, ranging from electron-withdrawing to electron-donating substituents. Using this series of monomers, in combination with 2,7-dialkylfluorene as a comonomer, five different conjugated polymers were prepared via Suzuki polycondensation, each having different electronic properties. The resulting copolymers exhibited M w values ranging from 5 to 10 kDa and PDI values in the 1.5–2 range. These polymers were characterized by 1 H NMR spectroscopy, optical spectroscopy, and cyclic voltammetry. Finally, a coumarin-containing oligomer was synthesized and used to demonstrate a photo-cross-linking scheme via [2 + 2] cycloaddition.

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
