Abstract

fetched live from OpenAlex

Abstract A series of coumarins were reacted with methacrylate or styrene derivatives to form new olefinic coumarin monomers that were polymerized using 2,2′‐azoisobutyronitrile (AIBN). These polymers were highly insoluble in organic solvents and displayed good thermal stability with glass‐transition temperatures between 70 °C and 130 °C. Luminescence studies on some of the coumarin‐containing polymers (CCPs) showed some fluorescence ( Φ F around 0.1). Some of the newly‐prepared coumarins and benzocoumarins were reacted with azo dyes to form mixed coumarin‐azo dye complexes. These mixed complexes were further reacted to prepare acrylic monomers and polymerized using AIBN. These polymers were thermally stable and poorly soluble in organic solvents. magnified image

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.
