Desolvation-Induced Network Reformation and Cracking in the Single Crystals of Hydrogen-Bonded Frameworks Composed of Tetraazaanthraquinone and Anthraquinone Derivatives.
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 8 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
A molecular-level understanding of how structural transformations induce morphological changes in organic crystals is essential for developing flexible crystalline materials. Herein, we report that two solvated hydrogen-bonded organic frameworks (HOFs) undergo structural transformations, giving rise to crystal crack propagation in the directions corresponding to their molecular displacements. The HOFs are composed of the tetracarboxylic acids, 4,4',4″,4'″-(5,10-dioxo-5,10-dihydropyrazino[2,3-g]quinoxaline-2,3,7,8-tetrayl)tetrabenzoic acid (TAAQ) and 4,4',4″,4'″-(9,10-dioxo-9,10-dihydroanthracene-2,3,6,7-tetrayl)tetrabenzoic acid (AQ), incorporating tetraazaanthraquinone and anthraquinone cores, respectively. Although TAAQ and AQ have closely similar molecular geometries, their HOFs have entirely different hydrogen-bonded networks. In both HOFs, we found that specific directional hydrogen bonds cleaved, and new hydrogen bonds re-formed, resulting in quasi single-crystal-to-single-crystal transformations. The direction of molecular displacement and crystal cell shrinkage were aligned parallel to the crack propagation. These results contribute to a deeper understanding of the underlying micro-macro property correlations induced by hydrogen-bond cleavage and re-formation.
