Mixtures of Tertiary Amine-Functionalized Mesogens with Poly(acrylic acid)
Bibliographic record
Abstract
Diethylamine-functionalized alkoxy methoxy biphenyl mesogens of variable spacer lengths (LC-1, n N, n = 5−12) and their equimolar mixtures with poly(acrylic acid) (PAA) were investigated by infrared spectroscopy, differential scanning calorimetry, polarizing optical microscopy, and X-ray diffraction. The pure LC-1, n N are polymorphic, generally possessing two different crystalline phases [a (full or partial) bilayer at ambient temperature followed by an orthogonal monolayer at higher temperatures], whose detailed characteristics depend on the spacer length. The mesogen melting point (a lamellar E-like−isotropic transition) is independent of spacer length. The equimolar LC-1, n N/PAA mixtures are biphasic, composed of a mesogen-pure phase and a phase composed of a polymer−mesogen complex resulting from proton-transfer interactions. The former is unperturbed by the presence of the latter. The complexes are liquid crystalline, most likely in the form of a partial or interdigitated smectic A mesophase. The smectic−isotropic transition temperatures are generally higher than the mesogen melting points and increase strongly with spacer length.

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.
