Precise synthesis of advanced polyarylamines for efficient perovskite solar cells.
Article in Nature materials, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Although being highly demanded in organic electronics, functional conjugated polymers face challenges on scalable synthesis with batch uniformities. Here a reactivity-regulated sequent cross-coupling carbon-nitrogen polycondensation method is developed to enable the precise synthesis of functional polyarylamines with excellent batch-to-batch uniformity. It is revealed that the stepwise regulation of intermediate reactivities is key to accomplish controllable polycondensation via two sequent palladium-promoted carbon-nitrogen coupling cycles, which is distinct to the unicyclic carbon-carbon coupling. A variety of polyarylamines are prepared to improve the material functionalities, where a ternary polymer consisting of polar substituents is shown to optimize the interfacial and bulk properties of perovskite layers fabricated on top. The corresponding inverted perovskite solar cells achieved remarkable power conversion efficiencies of 25.2% (active area, 5.97 mm
