Abstract

fetched live from OpenAlex

The calculated and observed vibrational spectra of a new series of perylene tetracarboxylic derivatives (PTCDs) with different alkyl lateral chain lengths (5, 10, 15, and 20 C) are reported. With the use of characteristic vibrational modes, the question about the degree of molecular organization and packing in these PTCD evaporated films has been resolved by using transmission and reflection-absorption infrared spectroscopy (RAIRS) techniques. From vibrational analysis, it was extracted that the molecules are preferentially oriented with the PTCD moiety head on the surface substrate. The molecular organization detected (by using RAIRS) in the evaporated films is not changed when the films are exposed to different solvents, such as water, methanol, and propanol, or when they are annealed up to 155 °C under normal atmospheric conditions or in vacuum. Evidence of molecular packing in the evaporated films is also provided by the observation of strong excimer emission.

Full frame distilled prediction

Teacher imitation

Not 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.
