Narrowband helical emitter with frontier orbital confinement for stable deep-blue hybrid-tandem organic light-emitting diodes.
Article in Nature materials, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Achieving efficient, stable deep-blue organic light-emitting diodes (OLEDs) with high colour purity remains challenging due to the scarcity of emitters combining narrowband emission and high stability. Here we present a multiple-resonance emitter featuring a highly twisted helical configuration with spatially confined frontier molecular orbitals. This emitter decouples radiative transitions from structural distortion while mitigating spectral broadening from carbon-hydrogen bond repulsion and aggregation, exhibiting sharp emission at 460 nm with a full-width at half-maximum of only 12 nm in solution and nearly identical spectra across varying-polarity systems. A unicolour-hybrid-tandem OLED design integrating complementary exciton-harvesting mechanisms to overcome the efficiency-lifetime trade-off is proposed, achieving an external quantum efficiency of 39.7% and a lifetime of 539 h to 90% of 1,000 cd m⁻
