Linear and branched supramolecular polymers formed from isomeric monomers as revealed by solution viscoelasticity.
Article in Chemical science, 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
Supramolecular polymers (SPs) assembled through non-covalent interactions provide a promising platform for designing soft materials with dynamic and tunable properties. However, the viscoelastic properties of their solutions remain poorly understood, largely due to the tendency of SP chains to bundle into thick supramolecular fibers, often resulting in precipitation or gelation. In this study, we show that bundle formation can be effectively suppressed by appropriate design of the surface of SPs through alteration of their side chains. Structural analyses revealed that the resulting SPs are homogeneously solvated, permitting their rheological characterization. Notably, we found that even subtle modifications, such as positional isomerism of the side chains, can dramatically alter the physical properties of SP solutions. Our findings, therefore, highlight the critical role of side chains in governing hierarchical structures and macroscopic properties of SPs, offering a design strategy for engineering functional supramolecular materials.
