Solution-Processable, Ladder-Branched Polyimides of Intrinsic Microporosity by [4+4] Cycloaddition for Membrane Gas Separation.
Article in Advanced materials (Deerfield Beach, Fla.), 2026. 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
Advancements in membrane-based gas separation have the potential to address global challenges related to energy and the environment. However, new membrane materials must have excellent separation performance, stability, and processability, and simultaneously achieving all three metrics is extremely challenging. To circumvent these issues, a post-synthetic modification of polyimides of intrinsic microporosity (PIM-PIs) synthesized with a UV light (UV)-reactive anthracene co-monomer is reported. UV irradiation on the PIM-PI solution converts the anthracene units into dianthracene linkages by [4+4] cycloaddition, while the resultant PIM-PI is still solution-processable due to the branched structure. The ladder-like dianthracene moieties significantly increased both microporosity (<20 Å) and ultramicroporosity (<7 Å) of the precursor PIM-PI. Notably, the UV-treated PIM-PI membrane exhibits a large boost in pure-gas CO
