Abstract

fetched live from OpenAlex

Abstract Diarylethenes (DAE) are a well‐known class of photochromic compounds with diverse applications ranging from optoelectronic devices to biological sensors. DAEs exhibiting emission in the closed form show potential for super‐resolution imaging, however, these are rare because DAEs in the closed form are notorious fluorescence quenchers. Here a series of DAE compounds containing phosphine oxide groups is reported that exhibit turn‐on emission and are the first examples of DAEs showing both aggregation‐induced emission (AIE) and anti‐Kasha emission in the closed form. The molecular design of the DAEs originates from careful selection of diphenylphosphine oxide groups, which have the appropriate bulkiness and electron‐withdrawing ability. Furthermore, the emission wavelength can be tuned by substituents, leading to a new class of diarylethenes that hold promise for applications including super‐resolution imaging.

Teacher imitation

Not 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.
