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

Control over luminescent properties is conventionally achieved by designing rigid, static packing geometries. Yet, chromophores within these assemblies naturally undergo continuous relative motion; harnessing this often-overlooked dynamic flexibility to actively dictate excited-state outcomes offers a powerful new dimension in materials design. Here, we introduce a supramolecular strategy to systematically control dual emission by restricting the structural dynamics of macrocycle-confined dimers. Utilizing cucurbit[8]-uril (CB[8]) macrocyclic host and bis-(phenylpyridinium) (BPP) guests, we construct precise 2:1 and 2:2 host-guest complexes to establish dynamic and static mobility limits within a unified framework. Cavity-confined dimerization induces a unique intrinsic dual emission. By progressively tightening structural restrictionmoving from the fluxional 2:1 complex to the clamped 2:2 architecture, and further to a rigidly sodium-bridged frameworkthe dominant emission cleanly shifts from a short-wavelength state to a long-wavelength state, accompanied by a dramatically enhanced fluorescence quantum yield. Time-resolved spectroscopy reveals that this supramolecular confinement actively governs the kinetics of excited-state relaxation, definitively linking motional freedom to the resulting functional photoluminescence. Collectively, these results showcase the controlled restriction of supramolecular dynamics as an innovative, general design principle for tailoring programmable optoelectronic materials.
