A New Class of Cationic Organoiron Polynorbornenes Containing Azo Dyes
Bibliographic record
Abstract
Abstract Ring‐opening metathesis polymerization of novel organoiron norbornene monomers functionalized with azobenzene chromophores using the Grubbs catalyst resulted in the production of the corresponding cationic organoiron polynorbornenes. UV‐vis analysis of the organometallic polymers in DMF showed maxima from 420–430 nm, and upon acidification a bathochromic shift to 510–520 nm was observed. Cyclic voltammetric studies showed that the iron centers underwent reversible reduction steps between −1.2 and −1.4 V. Thermogravimetric analysis of the organoiron polymers showed two weight loss steps from 225 to 255 °C and from 400 to 510 °C. Differential scanning calorimetry showed that the cationic organoiron polynorbornenes had glass transition temperatures (Tg) between 145 and 178 °C, while the Tg values of their organic analogs occurred between 99 and 104 °C. image

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.
