Synthesis and Characterization of Water-Soluble Cationic and Anionic Polythionylphosphazene Polyelectrolytes
Bibliographic record
Abstract
Convenient synthesis of a range of water-soluble polythionylphosphazene polyelectrolytes is reported. Facile reaction of 3-(dimethylamino)propylamines with the substitutionally labile poly(chlorothionylphosphazene) 2, which is generated via thermal ring-opening polymerization of the cyclic thionylphosphazene 1, afforded the water-soluble polymer 5 . The cationic polymer 6 was obtained upon quaternization of the dimethylamino groups in polymer 5 in the presence of dimethyl sulfate. The luminescent cationic polymer 7 was prepared through the covalent attachment of 30 mol % loading of an amino-functionalized ruthenium phenanthroline complex in the polythionylphosphazene side chains. The anionic polymeric precursor 14 was synthesized via substitution reactions of poly(chlorothionylphosphazene) 2 with amine 12 . Upon removal of the protective silyl groups, the anionic polythionylphosphazene 15 was obtained. All three polyelectrolytes 6, 7, and 15 were readily soluble in water, making them potentially useful materials for a range of applications.

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.
