Synthesis Of cyclic polymers with active esters for the preparation of functional materials
Bibliographic record
Abstract
Universal cyclic scaffolds of acrylate polymers with pentafluorophenyl active ester groups were synthesized using the α, ω- ring closing method and confirmed with a variety of characterization techniques. The incorporation of the active ester into the universal scaffold allows for alteration of the side groups by post polymerization modification. The preparation of this universal cyclic scaffold lays the synthetic foundation for materials that take advantage of cyclic polymer properties. Prerequisite linear poly(pentafluorophenyl methacrylate) was prepared possessing well-defined photoactive end groups and the conditions for the hetero Diels-Alder ring closing reaction were optimized. The synthesis of a series of phenanthridine and quinolone based fluorophores was explored for post polymerization modification. A series of linear and cyclic polymers with active esters were substituted to comparable degrees with a phenanthridine-based fluorophore and of the two topologies the cyclic polymers exhibited the expected enhanced emissivity.

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.
