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 machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
