Liquid Crystal Photoalignment using New Photoisomerisable Langmuir-Blodgett Films
Bibliographic record
Abstract
We present optical alignment studies of pure nematic liquid crystals using photoisomerisable Langmuir-Blodgett (LB) alignment layer. Monolayers of azobenzene-containing molecules exhibiting long lifetime for cis isomer are transferred on glass substrates using the Langmuir-Blodgett deposition technique. The anchoring produces homeotropic texture and the strength of this anchoring is increasing with increasing number of monolayers from 1 to 7. The exposition of the cells with UV light the spectrum of which corresponds to the absorption band of the dye in the trans conformation induces strong realignment of the LC molecules via the trans-cis photoisomerization process and the regulation of the film orientation by LCs. Such reorientation occurs mainly in the plane perpendicular to the polarization plane of the excitation.

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.
