Abstract
2-Ureido-4[1H]-pyrimidinone (UPy) is widely deployed in bulk materials for switching phase or physical cross-linking because of exceptional quadruple H-bond strength and thermal reversibility. However, utilization of UPy dimers as the switching phase to prepare shape memory hydrogels has been rarely explored due to the competition with water molecules. Herein, hydrogels with high UPy contents are synthesized and exhibit excellent shape memory ability, even at high water contents. By introduction of tetraphenylporphyrin into hydrogels, the shape memory behavior can further be controlled by light through a photothermal effect. This finding offers possibilities for applications of UPy in developing shape memory hydrogels.

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 it
