Abstract

fetched live from OpenAlex

This study reports a new simple organic semiconductor 2,6‐bis(4‐methoxyphenyl)naphthalene (BOPNA) with unprecedentedly large band gap of 3.35 eV and an apparent hole mobility of ≈1 cm 2 V –1 s –1 measured in thin‐film organic field‐effect transistors in a saturation regime. This large band gap leads to complete optical transparency in the visible range (>370 nm), very high stability and independence of the device current with illumination conditions; this is in contrasts to the behavior of common organic semiconductors that have the band gap in the visible or near‐IR range of the spectrum. Crystal structure of BOPNA reveals a highly isotropic electronic coupling in two directions of a herringbone‐packing plane. A uniform, nearly single crystalline morphology can be achieved in highly crystalline BOPNA films through a rapid thermal annealing. Temperature‐dependent studies reveal increase of the hole mobility as the temperature is reduced from +25 to –25 °C, suggesting a band‐like transport, followed by a nearly temperature‐independent mobility down to at least –150 °C.

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.
