Modulating Chalcogen Bonding and Halogen Bonding Sigma-Hole Donor Atom Potency and Selectivity for Halide Anion Recognition.
Article in Angewandte Chemie (International ed. in English), 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 25 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 series of acyclic anion receptors containing chalcogen bond (ChB) and halogen bond (XB) donors integrated into a neutral 3,5-bis-triazole pyridine scaffold are described, in which systematic variation of the electronic-withdrawing nature of the aryl substituents reveal a dramatic modulation in sigma-hole donor atom potency for anion recognition. Incorporation of strongly electron-withdrawing perfluorophenyl units appended to the triazole heterocycle telluro- or iodo- donor atoms, or directly linked to the tellurium donor atom dramatically enhances the anion binding potency of the sigma-hole receptors, most notably for the ChB and XB receptors displaying over thirty-fold and eight-fold increase in chloride anion affinity, respectively, relative to unfluorinated analogues. Linear free energy relationships for a series of ChB based receptors reveal the halide anion recognition behaviour of the tellurium donor is highly sensitive to local electronic environments. This is especially the case for those directly appended to the Te centre (3⋅ChB), where a remarkable enhancement of strength of binding and selectivity for the lighter halides is observed as the electron-withdrawing ability of the Te-bonded aryl group increases, highlighting the exciting opportunity to fine-tune anion affinity and selectivity in ChB-based receptor systems.
