Main-chain photoresponsive polymers with controlled location of light-cleavable units: from synthetic strategies to structural engineering
Bibliographic record
Abstract
Photoresponsive polymers have gained more and more attention in recent years since light stimulation can be spatiotemporally localized and controlled. In general, photoresponsive polymer structures are classified into two categories: one is for polymers in which the chromophores are positioned in the side-chain as pendants; while the other one covers polymers whose photoresponsive species are catenated onto the chain backbone. Since there are a number of reviews dealing with the first category, we turn our sight to focus on the main-chain photodegradable polymers, highlighting the recent progress and the rapidly expanding spectrum of well-defined light-sensitive architectures. On the basis of the variety of synthetic strategies for incorporating the photosensitive functionalities into the polymer chain, one could rationally design and construct main-chain photodegradable polymers with diverse macromolecular structures and functions. Finally, we suggest the possible future directions and perspective in this area.

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.
