Beyond Common Energy Transfer: Intramolecular Electron Transfer Cascade Controls Triplet Population of a Long-Lived Iron-Anthracene Molecular Dyad.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
An iron-anthracene dyad was recently used to populate a microsecond-lived nonluminescent (dark) triplet state, but with a surprisingly low triplet population yield. In-depth spectroscopic experiments highlight that direct energy transfer does not take place, but rather an intramolecular electron-transfer occurs, generating the corresponding reduced iron center and oxidized anthracene moiety, and the final triplet dark state is populated following charge recombination. This electron-transfer cascade reaction mechanism provided the unique opportunity to control the energy level of the charge-separated state relative to the energy of the triplet state by changing the solvent polarity. As such, the triplet formation yield increased from 5% in acetonitrile to 75% in dichloromethane. This outlines an unreported mechanistic pathway for first-row transition metal complexes to populate long-lived excited states and provides design guidelines that differ between d
