Langmuir−Blodgett Mixed Films of Titanyl(IV) Pthalocyanine and Arachidic Acid. Molecular Orientation and Film Structure
Bibliographic record
Abstract
Langmuir and Langmuir−Blodgett (LB) films of neat titanyl(IV) phthalocyanine (TiOPc) and mixed (TiOPc)−arachidic acid (AA) films were studied. The surface pressure−area isotherms (π− A ) were recorded, and an unusual expansion of the surface area per molecule was detected for mixed TiOPc−AA Langmuir monolayers. The expansion is attributed to the TiOPc molecular orientation in the neat films being different from that in the mixed films with arachidic acid. The molecular orientation in LB films was monitored using reflection−absorption infrared spectroscopy (RAIRS). It was found that the TiOPc molecules are tilted with respect to the substrate in the neat film, changing to a preferential face-on orientation in the TiOPc−AA mixed films. Complementary information about molecular organization and film structure was obtained using UV−visible absorption and micro-Raman imaging.

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.
