Preparation of novel fluorinated highly branched (<scp>A<sub>3</sub></scp> + <scp>B<sub>3</sub></scp>)‐type hyperbranched poly(amide‐imides) for electrochromism and iodine adsorption
Bibliographic record
Abstract
Abstract In this study, a series of (A3 + B3)‐type fluorinated hyperbranched poly(amide‐imides) were successfully synthesized with carbazole and fluorene units as end‐capping moieties. All synthesized end‐capping hyperbranched PAIs showed over 70% branching as determined by 1H NMR, demonstrating good solubility and thermal stability (Tgs: 242–263°C, T10%: 576–629°C). The HOMO and LUMO energy levels of hyperbranched PAI films were measured at 4.65–4.73 and 1.51–1.66 eV, respectively, suggesting favorable reoxidation and reduction characteristics. PAI‐2 demonstrates a 46.6% transmittance variation (∆T, 418 nm), along with a coloring/bleaching process time of 2.3 s/1.6 s, a coloring efficiency (CE) of 310 cm2/C, and exceptional redox stability over 100 cycles. Furthermore, the synthesized PAIs containing electron‐withdrawing groups exhibited a high iodine adsorption capacity as determined by iodine adsorption tests (PAI‐1: 534 mg/g, PAI‐2: 579 mg/g, PAI‐3: 490 mg/g).

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.
