Abstract
Comprehensive Summary Modulating the photophysical of organic solid‐state functional materials is crucial for advancing supramolecular chemistry and materials science. Here, we present a π‐conjugation enhanced charge‐transfer strategy to turn on the photothermal conversion properties of crown ether cocrystals. Three crown ethers ( H 1 , H 2 , and H 3 ) bearing different π‐conjugated moieties are synthesized, exhibiting enhanced solid‐state luminescence upon increasing molecular conjugation. In addition, three sets of host–guest cocrystals are constructed via charge‐transfer (CT) interactions between these electron‐rich crown ethers and electron‐deficient 1,2,4,5‐tetracyanobenzene ( TCNB ). Based on the variations in CT interactions, the resulting cocrystals transform from primarily photoluminescent behavior to efficient photothermal conversion. Detailed structural and spectroscopic analyses reveal that the extent of π‐donor/π‐acceptor overlap within the cocrystals is the dominant factor governing their tunable photophysical properties.

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
