Poly(p-phenylene phosphaborene): A Modified Poly(p-phenylene vinylene) with π-Conjugated B═P Linkages.
Article in Angewandte Chemie (International ed. in English), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
While the isoelectronic substitution of selected C═C by B═N units in π-conjugated organic compounds has evolved into a well-established concept to create novel hybrid materials with modified properties, the use of valence isoelectronic B═P units for such purposes has been hardly explored. Herein, we demonstrate substitutional doping of the famous optoelectronic organic polymer poly(p-phenylene vinylene) (PPV) with B═P linking groups for the first time. We report on the successful synthesis of a soluble polymer and a series of monodisperse oligomers of BP-PPV type. Our structural and photophysical investigations, supported by in-depth DFT calculations, evidence effective π-conjugation along their backbone, which is similary pronounced as in their previously reported BN congeners. In addition, the novel BCP compounds show distinct fluorescence emission in solution and emission enhancement upon aggregation (AIEE), occurring from a P-pyramidalized excited state.
