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

The innovative design of π-conjugated molecules enables the creation of chiral π-systems that selectively interact with circularly polarized light. In circularly polarized organic photodetectors, the use of π-conjugated molecules with highly dissymmetric circularly polarized absorption has been a key strategy for achieving strong differential electrical signals with circularly polarized light. However, factors beyond absorption that influence asymmetric device behavior remain insufficiently explored. In this work, we demonstrate trap-assisted circularly polarized organic photodetectors based on blend systems containing small amounts of achiral acceptors, enabling asymmetric trap filling depending on the handedness of circularly polarized light. Modulated trap dynamics play a crucial role in asymmetric charge extraction, significantly enhancing circularly polarized selectivity. We realize a large-area organic circularly polarized imaging system (4096 pixels) and showcase its potential for real-time visual encryption. This study presents a design strategy for efficient circularly polarized photodetectors with tailored carrier dynamics.
