Abstract

fetched live from OpenAlex

A new strategy for the preparation of azo-containing liquid crystalline polymers is presented. A polymethacrylate bearing an azopyridine group in the side chain was synthesized for the first time. The amorphous azopyridine polymer can easily be converted into liquid crystalline polymers through self-assembly with a series of commercially available, aliphatic and aromatic carboxylic acids including the acetic acid. The measurement of photoinduced birefringence reveals that these complexes may have very different behaviors. The study thus shows that azopyridine side chain polymers combine the photoactivity of azobenzene polymers with the capability of self-assembly promoted by the pyridyl group, which offers a new and robust approach toward the preparation and exploitation of photoactive liquid crystalline materials.

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.
