Abstract

fetched live from OpenAlex

Abstract Synthetic efforts toward the preparation of rotaxane precursors based on phenylacetylene macrocycles (PAM) are described. The aim of this study was to determine the optimal structural parameters to prepare high‐molecular‐weight rotaxane precursors through a strategy involving two Sonogashira couplings to attach bulky blockers on the PAM core. PAMs with different sizes and functions were prepared and coupled to different blockers to assess whether or not the resulting structure adopts a rotaxane‐like conformation in which the rigid rod forms after the Sonogashira coupling threads through the PAM.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Teacher imitation

Not 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.
