N-Ethylcarbazole as a structure-directing agent in poly[(ethynediyl)(arylene)(ethynediyl)silylene]–poly(phenylsilsesquioxane) hybrid nanomaterials exhibiting photorefraction at telecommunication wavelengths
Bibliographic record
Abstract
Self-organisation through π-stacking occurs in poly[(ethynediyl)(arylene)(ethynediyl)silylene]–N-ethylcarbazole–poly(phenylsilsesquioxane) compositions giving rise to nanostructured hybrid layered materials exhibiting photorefraction at telecommunication wavelengths. To our knowledge, this is the first such material to be reported the poly[(ethynediyl)(arylene)(ethynediyl)silylene] acting as an optical chromophore, charge generator and conductor. The absorption band tails into the near-IR hence providing charge generation at 1500 nm excitation. The photorefractive response was investigated by using a two-beam coupling technique. The gain of the probe beam intensity, delivered from the pumping beam, reached 40 cm−1 with an electric field strength of 650 kV cm−1 thus confirming the photorefractive nature of the grating. The gain exceeded the absorption (30 cm−1) hence showing the high potential of this material for practical applications.

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.
