Installation of cationic phosphorus on dimethyldihydropyrene photoswitches: expanding the atomic repertoire towards far-red photoswitching in water
Bibliographic record
Abstract
We have synthesized for the first time a small library of negative photochromic dimethyldihydropyrene phosphonium salts (DHPPs) that can be activated by red and far-red (up to 740 nm) photons in a quantitative manner in the so-called "biological window". The intriguing feature of this particular class is their remarkably fast response in fully aqueous media with an improved ring-opening quantum yield. Additionally, the reversal can be activated upon visible (blue) light irradiation and also under thermal conditions in a quantitative manner, achieving efficient bidirectional visible light-mediated switching rendering this particular class of photoswitches even more attractive towards their potential application in biological premises. Additionally, all-photonic orthogonal photoswitching of a mixture of conventional unsubstituted DHP and one of our modified DHPP derivatives provides a demonstration of multifunctional molecular logic operations.

How this classification was reachedexpand
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.
