1 · What the graph read from it

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.

2 · The registry

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

Coordination-driven self-assembly is a facile and powerful strategy for the construction of metallosupramolecular mechanically interlocked molecules (MIMs). However, the limited stability of most MIMs constitutes a challenge with respect to the evaluation of their practical applications. Herein, we demonstrate a rational strategy to control the self-assembly outcome for selected metallosupramolecular structures. The reaction of a biphenyl-bridged bisimidazole ligand with dinuclear building blocks of varying lengths leads, depending on the size of the dinuclear building block, to a simple [1+1] metallacycle, a twisted [2+2] three-dimensional trapezoidal structure, or an intricate [3+3] metallosupramolecular trefoil knot. The trefoil knot exhibits exceptional structural stability, resisting decomposition upon dilution in polar solvent. Its knotted topology enforces strong intramolecular π⋅⋅⋅π stacking interactions, which red-shift the absorption band into the near-infrared (NIR) region. Benefiting from its stability and NIR absorption, the trefoil knot displays a high photothermal conversion efficiency (η = 73.5%) and a potent photoacoustic (PA) effect in water, even at low concentrations.
