Strain-Induced Quinoidal Character in a Carbon Nanoring Embedding Anthracene Units.
Article in Journal of the American Chemical Society, 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
We report a carbon nanoring, [2.2]cyclo(9,10)anthrylene-paraphenylene ([2.2]CAPP), featuring alternating anthracene and phenylene units within a [4]cycloparaphenylene (CPP) framework. The molecule was synthesized via a six-step metal-free route and structurally characterized by single-crystal X-ray diffraction. The high ring strain induces significant distortion in the anthracene units, resulting in a quinoidal electronic structure with a suppressed aromaticity. Despite possessing a 16π-electron conjugation pathway, no global antiaromaticity was observed. This work demonstrates that strain engineering in carbon nanorings enables control over the aromaticity and open-shell character through rational molecular design.
