Variable Composition Mixtures of a Tertiary Amine-Functionalized Mesogen and Poly(acrylic acid)
Bibliographic record
Abstract
Mixtures of a diethylamine-functionalized dodecyloxy methoxy biphenyl mesogen and poly(acrylic acid) (PAA) were investigated as a function of composition by infrared spectroscopy, differential scanning calorimetry, polarizing optical microscopy, and X-ray diffraction. The data obtained indicate that the components form a monophasic supramolecular complex for amine/acid molar ratios below about 0.5 and a biphasic system composed of the supramolecular complex and a mesogen-pure phase for higher molar ratios. The complex gives rise to a smectic A mesophase that becomes isotropic at 147 °C for molar ratios down to about 0.3. An E-like phase is detected in the complexes of 0.4 and 0.5 molar ratios after lengthy annealing. The complex in the biphasic mixtures may also tend to E-like order below the melting point (crystal E-like−isotropic transition) of the mesogen-pure phase. The thermotropic transformation from E-like to smectic A order in the complex appears to be slow.

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.
