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 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.
