Abstract
The title thiophene derivatives bearing two 9-, 1-, or 2-anthryl groups were synthesized by cyclization of the corresponding 1,3-diynes with sodium sulfide or by Suzuki–Miyaura coupling. X-ray analysis and DFT calculations revealed that the molecules adopt nonplanar conformations depending on the steric demand of the anthryl groups. The dihedral angles between the arene units are an important contributor to the photophysical properties in the electronic spectra as well as the electrochemical data.

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 it
