1 · What the graph read from it

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.

2 · The registry

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

We designed and synthesized cinchona alkaloid derivates PMI-BnCPD, 1 and PMI-dHQD, 2, in which a fluorescent perylene monoimide unit is linked to the quinuclidine fragment. The latter acts as an electron donor, quenching the perylene imide fluorescence in polar solvents. In the organocatalytic application of these compounds, the electron donor is deactivated by binding to an electrophile, e.g. H+. We show that this restores the fluorescence, allowing the compounds to signal the electrophile binding step that occurs in many catalytic reactions. In order to demonstrate that charge transfer is indeed the fluorescence quenching mechanism, we detected the charge separated state by means of transient absorption spectroscopy. Incidentally, the excited state absorption bands of the locally excited and charge transfer states are very similar. The activity of the fluorophore labeled organocatalyst 1 in a fluorogenic Michael addition reaction is demonstrated.
