Expanding the Molecular Switches Toolbox: Photoreloadable Dithienylethene Mechanophores.
Article in Angewandte Chemie (International ed. in English), 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
Molecular switches are often thought of as nanoscopic equivalents to the electrical buttons and knobs ubiquitous in everyday life. However, mechanical force is rarely used to reversibly trigger rearrangements at the atomic scale, due to the difficulty in selectively breaking certain bonds, while keeping others intact. Here, we introduce two new mechanophores based on dithienylethene (DTE), which can be toggled between two states by ultraviolet light and sonication. Attaching various lengths of poly(ϵ-caprolactone) either to the 2,2' or the 5,5' positions of the DTE core allowed us to study the kinetics of its mechanochemical cycloreversion. We employed computational methods to understand the root causes of the observed mechano-regiochemical differences. Lastly, we show that our best performing DTE-polymer conjugate can undergo numerous switching cycles by the alternating action of electromagnetic radiation and mechanical force.
