Abstract

fetched live from OpenAlex

Organoplatinum(IV) complexes, [PtBrMe 2 (CH 2 -4-C 6 H 4 -N═N-Ph)(NN)], containing trans -azobenzene functional groups, have been prepared by trans oxidative addition of BrCH 2 -4-C 6 H 4 -N═N-Ph to the corresponding platinum(II) complexes [PtMe 2 (NN)], with NN = 2,2′-bipyridine, 1,10-phenanthroline, 4,4′-bis(ethoxycarbonyl)-2,2′-bipyridine, 1,4-di-2-pyridyl-5,6,7,8,9,10-hexahydrocycloocta[ d ]pyridazine. The complexes undergo efficient and almost quantitative trans – cis isomerization on irradiation of dilute solutions at 365 nm, as monitored by UV–visible spectroscopy, and somewhat less complete photolysis in concentrated solution, as monitored by 1 H NMR spectroscopy. The cis isomers undergo slow thermal isomerization back to the trans isomers, thus proving the photoswitching property of the complexes.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

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.
