Abstract

fetched live from OpenAlex

The synthesis of a class of highly pi-extended tetrathiafulvalene derivatives (1a and 1b) was explored using Sonogashira macrocyclization as a key step. The solid-state structure of 1b was characterized by X-ray single crystallography, showing a substantially bent, S-shaped molecular backbone and an ordered packing geometry in a pi-alkyl-alkyl-pi stacking fashion. Electronic and redox properties of 1b were investigated by UV-vis absorption, fluorescence spectroscopy, and cyclic voltammetry.

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.
