One-Step Direct Oxidation of Alkoxy to Ketone for Evaporable Fullerene-Fused Ketone as Efficient Electron-Transport Materials
Bibliographic record
Abstract
Abstract Ketones, one of widely applied moieties in designing electrical and medical materials, commonly converted from the alcohols through the oxidation reactions. However, when alcohols are protected/functionalized, the direct oxidation strategies are substantially curbed. Here we show a highly efficient copper bromide promoted one-step direct oxidation of alkoxy to ketone with the aid of a fullerene pendant. Mechanistic studies unveil that fullerene can serve as an electron poor proceeding the one-step oxidation of alkoxy group to ketone. In the absence of fullerene pendant, the unreachable activation energy threshold hampers the direct oxidation of alkoxy group. In the presence of fullerene pendant, copper bromide oxidized fullerene radical cation can activate neighboring C–H bond of alkoxy moieties, allowing a favorable energy barrier for initiating the direct oxidation of alkoxy group. Produced fullerene-fused ketone indicates high thermal stability, affording the pin-hole free and amorphous electron-transport layer with high electron-transport mobility.

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.
