Multicolor and multistable transparent electrochromic materials and displays.
Article in Nature communications, 2025. 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
Electrochromic (EC) displays attract growing interest as promising candidates for next-generation transparent displays due to their intrinsic high transmittance and excellent eye-friendly properties. However, achieving simultaneous high transparency and vivid multicolor switching remains challenging. Here, we present a single-molecule design strategy that integrates a rhodamine moiety with a ProDOT (3,4-propylenedioxythiophene) unit. Following systematic screening of molecular dopants, these systems demonstrate well-matched electrochemical potential windows and compatible redox behaviors, thereby effectively eliminating color interference. The as-prepared PTRh-B devices achieve high optical transmittance with three distinct optical states-colorless, magenta, and blue-and multiple stable states (colorless and blue states >5 h; magenta state >30 days). The devices also show excellent cycling stability of over 5,200 cycles for the colorless-to-magenta and 8,400 cycles for magenta-to-blue transitions, coupled with fast switching times of 0.13 s and 1.8 s, respectively. Moreover, functional pixel-level display is successfully realized, underscoring the significant potential for developing advanced transparent and energy-efficient display and electronic erasable memory systems.
