Electroclinic Effect In Unsymmetrical Dimeric Liquid Crystals Composed of Two Non-Identical Chiral Mesogenic Entities
Bibliographic record
Abstract
Abstract We report the synthesis and physical characterization of two unsymmetrical dimeric liquid crystals containing two different chiral mesogenic segments, namely, a tolan unit with (S)-2-octyloxy tail and a cholesteryl ester unit which are separated by a n-butyl (even) and n-pentyl (odd) spacers respectively. Both the dimers exhibit a smectic A mesophase, with the dimer having the n-pentyl spacer stabilizing this phase over a temperature range of ˜150°. Electro-optic studies performed on this compound show that it exhibits an observable electroclinic effect over this entire temperature range. At room temperature, the electroclinic tilt angle and the response time observed are comparable to those exhibited by some monomeric materials.

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; both teacher heads agree on what is shown here.
