Abstract
Abstract Substituting individual heavier (or lighter) atoms would appear to be an extremely straightforward method of controlling the optoelectronic properties of π‐conjugated molecules that has minimal impact on solid‐state materials properties, yet things are never as they appear. Selenophenes are a distinct class of material separate from thiophenes. Their HOMOLUMO gap is often narrow, which is attractive for photonic applications. Intermolecular SeSe interactions increase ordering on a molecular scale and lead to distinct solid‐state organization, which often leads to excellent charge‐transport properties. The crystallization of selenophene is distinct from thiophenes, and thus, composites of selenophenes and other organic materials have distinct nano‐ and microscale morphologies. Some of the best organic optoelectronic devices use selenophene‐containing materials, yet early results were less encouraging. The most recent syntheses, structure determination, and electronic device properties of π‐conjugated selenophene‐based materials are reviewed. Significantly more work is justified and this review sets the stage for those studies.

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.
