Photochromic Reaction of Diarylethenes Having Phenol Moiety as an Aryl Ring
Bibliographic record
Abstract
Abstract Three types of diarylethenes having one phenol moiety as an aromatic unit were synthesized in order to control pH change upon irradiation with UV and visible light. Upon irradiation with 313 nm light, these open-ring isomers were transformed to thermally unstable colored isomers in methanol solution. During the storage of the photoirradiated diarylethene solutions in the dark for 10 min, the thermally unstable closed-ring isomers were converted to thermally stable keto isomers. The structures of these isomers were characterized by 1H NMR and X-ray crystallography. The keto isomers were transformed to the initial phenol isomer upon irradiation with visible light. Additionally, we also found the formation of a novel photochromic diarylethene derivative having one keto group on the cyclopentane ring during UV irradiation. A pH change between the two isomers was observed in a mixture of ethanol and water.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
