Streamlined Access to Substituted Benzothieno-<i>S</i>,<i>S</i>-Dioxide-Benzofuran (BTOBF): Properties and Application in Solution-Processed Organic Light-Emitting Diodes
Bibliographic record
Abstract
Utilizing a streamlined five-step synthesis process, we have successfully produced a diverse set of adjustable benzo[4,5]thieno- S, S -dioxide-[3,2- b ]benzofurans-based compounds via Michael’s addition–elimination reaction, Suzuki-Miyaura coupling, and intramolecular oxidative C–H/C–H coupling, in 70–90% yields. The synthetic strategy employed demonstrates that the compounds can be modified on either side by introducing various types of groups at positions 2 and 3, with the possibility of extending the aromatic portion in place of benzofuran. Thus, these compounds exhibit a distinctive dual-state emission, showcasing very good quantum yields up to 63% in the solid state and 83% in solution. Additionally, these compounds were integrated into ambient conditions and solution-processed, nondoped OLEDs, demonstrating promising results with a luminance of 850 cd/m 2 and a turn-on voltage of 3.50 V.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
