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

Controlled doping of conjugated polymer-based semiconductors is crucial for optoelectronic applications. While p-type doping of conjugated polymers can be readily achieved with a variety of oxidants, n-type doping is more challenging, usually requiring highly reactive reducing agents. Here, we demonstrate that an air-stable photoredox catalyst (acridinium salt), together with a mild and air-stable reducing agent (amine), can effectively dope common n-type conjugated polymers under light at room temperature, yielding conductivity values on par with the highest obtained via other means. We elucidate the mechanism and show that this photoredox n-doping occurs via a one-photon-one-electron transfer process that is catalytic in nature. This simple and facile n-doping approach opens more avenues for doping organic semiconductors with the potential to revolutionize device design and substantially enhance doping efficiency.
