Electrodeposition of Oligothiophene-Linked Gold Nanoparticle Films
Bibliographic record
Abstract
The electrodeposition and characterization of conducting thin films of gold nanoparticles bridged with oligothiophene linkers are reported. Gold nanoparticles capped with the conjugated phosphines 5-diphenylphosphino-2,2‘:5‘,2‘ ‘-terthiophene ( d core = 1.7 ± 0.3 nm) and 5-diphenylphosphino-3‘,4‘-ethylenedioxy-2,2‘:5‘,2‘ ‘-terthiophene ( d core = 1.8 ± 0.4 nm) have been prepared. Electrochemical oxidation of these particles results in the deposition of thin films consisting of intact nanoparticles linked by oligothiophene moieties, in which the π−π* absorption of both the conjugated linker and the plasmon band are red-shifted relative to individual nanoparticles. Conductivities of both the unlinked and linked particles are measured and the latter are shown to have substantially higher conductivities than unlinked particles or gold nanoparticles linked by saturated alkyl chain linkers.

How this classification was reachedexpand
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.
