Optical Properties of a-Sexithiophene Dyes Aggregated inside Carbon and Boron Nitride Nanotubes
Bibliographic record
Abstract
The inner cavity of nanotubes attracted a lot of interest as template for the encapsulation of elongated dyes molecules, such as polythiophenes. Indeed, the 1D confinement drives the stacking of the molecules inside and enables original aggregation effects on their optical properties (1,2). When encapsulated inside carbon nanotube, the 6T exhibits for example a strong and specific Raman scattering but its luminescence is efficiently quenched by the nanotube (3). Here we show that the same dye, when encapsulated inside boron nitride (6T@BNNT) exhibits strong luminescence with signature of inter-molecules coupling (4). Photoluminescence imaging experiments on individualized 6T@BNNT deposited on substrate show that the encapsulation also prevents the bleaching of the molecules under strong photoexcitation, harsh oxidizing exposure and annealing in air up to 350°C.

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.
