Molecular rotation and large polarization in charge-transfer ferroelectric cocrystals.
Article in Nature chemistry, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Organic ferroelectrics offer solution processability, mechanical flexibility and promising applications in sensing, energy storage and actuation. However, their polarization and Curie temperatures are typically lower than those of inorganic ferroelectrics because weak intermolecular interactions hinder efficient dipole alignment. The development of organic materials that integrate dipole units, long-range dipole ordering and switchable polarization may enable the design of high-performance organic ferroelectrics. Here we report a donor-acceptor cocrystal in which V-shaped donor molecules pack into a gear-like arrangement, enabled by supramolecular interactions. Within this binary confined lattice, a cooperative in-plane rotation of 42° by the donor molecules-triggered by an external electric field-enables reversible polarization switching. This rotational mechanism yields a remanent polarization of 58 μC cm
