Abstract
Donor–acceptor–donor arrays based on an anthracene bisimide (ABI) skeleton appended with 6,13-diethynylpentacene and 9,10-diethynylanthracene units have been constructed by Sonogashira coupling followed by reductive aromatization. Their photophysical and electrochemical properties are compared with those of the corresponding mono-substituted analogs on the basis of theoretical calculations and cyclic voltammetry to evaluate the intramolecular electronic interactions between ABI as the acceptor unit and diethynylacene as the donor unit. The title donor–acceptor–donor arrays were synthesized by Sonogashira coupling followed by reductive aromatization. These molecules showed intramolecular electronic interactions between ABI as the acceptor unit and diethynylacene as the donor unit via ethynyl linkers.

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
