Thermotropic Liquid Crystalline Complexes of Hydrogen-Bonded Poly(pyridylpyridinium dodecyl methacrylate) Bromide and Octylphenol
Bibliographic record
Abstract
An ion-containing polyamphiphile, poly(ω-pyridylpyridinium dodecyl methacrylate) bromide, was successfully complexed with 4-octylphenol by hydrogen bonding, with no interference from the ionic moieties. Hydrogen bonding of the surfactant to the polymer is virtually complete up to near-equimolar phenol/pyridyl ratios. The complexation generates a well-behaved thermotropic liquid crystalline system from a low-melting surfactant and a polymer with ill-defined mesomorphism. The complex melts at relatively high temperatures into a liquid crystalline (smectic A) phase before becoming isotropic. The long period of the mesophase is almost identical to that of the polyamphiphile alone, is between the calculated lengths of the uncomplexed and complexed polymer repeat units, and is essentially independent of the complex stoichiometry. This can be rationalized by the same model presented in a previous publication for an ionically complexed polyamphiphile−surfactant system.

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.
