Preparation of Poly(silylene-<i>p</i>-phenylene)s Bearing a Benzo Crown Pendant Group and Their Iono- and Solvatochromic Behavior in the Emission Spectra
Bibliographic record
Abstract
Poly(silylene- p -phenylene)s bearing a benzo crown pendant group were obtained as colorless solids in moderate yield by the reactions of poly[chloromethyl- or ethoxymethylsilylene- p -phenylene] with lithiated benzo crown ethers in THF. The benzo crown substituted polymers responded to selected alkali-metal or alkaline-earth-metal ions in the emission spectra, depending on the crown ether ring size. Thus, when appropriate metal ions were added to the polymer solutions, the intensity of a maximum broad emission band around 400 nm decreased and a band at about 320 nm was markedly enhanced. Similar chromism of the polymers was also observed, depending on the solvent polarity in the absence of metal ions.

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.
