Abstract

fetched live from OpenAlex

Abstract Poly(3‐hexylthiophene) was quantitatively brominated and subsequently used in the Suzuki cross‐coupling with a boronic ester of a nitroxide to form a macroinitiator bearing a TEMPO group on each thienyl ring. This macroinitiator initiated the nitroxide‐mediated radical polymerization of styrene and 4‐chloromethylstyrene (CMS), and subsequently reacted with C60 to yield soluble graft, rod‐coil polymers. Films of the polymers display a bi‐continuous phase structure as revealed by AFM. Similar polymers, in which only a fraction of the thienyl units boasted C60‐bearing side chains, displayed optical properties representative of extensive π‐delocalization. The potential application of this methodology for the synthesis of graft polymers for photovoltaic devices is discussed. magnified image

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
