Poly(imidoaryl ether)s with bulky highly fluorescent pendent groups
Bibliographic record
Abstract
Abstract Three novel aromatic imidoaryl bisphenols 6a–c with bulky groups of varying size on the pendent phenyl ring have been synthesized from 3,8‐bis(4‐hydroxyphenyl)‐N‐phenyl‐1,2‐naphthalimide 1a. Poly(imidoaryl ether)s were synthesized in dipolar aprotic solvents by reacting the monomers with activated difluoro compounds. Glass transition temperatures (T g) for the polymers are in the range 265.9–315.0 °C, and they exhibit a range of colors from yellow to red. The highest T g and 5% weight loss temperature of these polymers were 315 and 496 °C, respectively. Most of the polymers are soluble in chloroform at room temperature. The UV‐vis absorption spectra of polymers 11ae, 11be and 16 were recorded in chloroform. Polymer 16 has the most intense absorption peaks (above 300 nm) at 492 and 528 nm, respectively, while the fluorescent spectrum of polymer 16 shows several peaks at 428, 539, 577 and 625 nm, respectively, when excited at 350 nm.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
