The synthesis of organoiron complexes and coordination polymers containing functionalized terpyridines
Bibliographic record
Abstract
Organic terpyridine derivatives were prepared via nucleophilic substitution at the 4′-position and coordinated with iron, ruthenium, or nickel to form several chelated complexes. These chelated compounds were reacted with chloro-terminated organoiron carboxylic acid complexes to afford terpyridine-based monomers containing three metal centres. A monomer containing a cationic iron complex with two terminal terpyridine moieties was synthesized by employing a Steglich esterification between a dicarboxylic acid organoiron complex and a hexanediol-functionalized terpyridine. The monomers containing multimetal centres were polymerized through nucleophilic aromatic substitution reactions with bisphenol A or hydroquinone, while the monomer containing one organoiron moiety and terminal terpyridine groups was polymerized through chelation to iron or nickel. The thermal properties of the polymers were investigated, with differential scanning calorimetry providing glass transition temperatures of approximately -21 °C for the iron-chelated polymers. Thermogravimetric analysis showed stepwise degradation of the cationic iron moieties, followed by the aromatic backbone, with the final decomposition step representing the loss of the bonding interaction between the iron centre and the nitrogen atoms of the chelated terpyridine groups.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
