Photochemical and Direct <scp>CH</scp> Arylation Routes toward Carbon Nanomaterials
Bibliographic record
Abstract
This chapter presents a recent literature survey of both the intramolecular photochemical and direct CH arylation reactions to prepare polycyclic aromatic hydrocarbons (PAHs) and carbon nanomaterials fragments. The photochemical dehydrogenation, or Mallory reaction, is probably the most widely spread photochemical method for the preparation of carbon nanomaterials and PAHs. The chapter focuses on the synthesis of carbon nanomaterials and PAHs through photochemical dehydrogenation reaction, more specifically on the Mallory and Katz-modified Mallory photocyclization reactions. Recently, the Katz-modified reaction was used as a key step toward the synthesis of large PAHs, especially coronene derivatives. The direct CH arylation is a very popular synthetic method nowadays for the preparation of conjugated molecules, especially Π-conjugated polymers. The photochemical and direct CH arylation methods are leading examples of recent advances that will certainly contribute to broaden the PAHs family and improve their properties in regards to their use as active component in electronic devices.

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.
