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

Controllably achieving multicolor emission from single-molecule-based organic solids is of great significance, yet it remains a challenge because of the inherent complexity of molecular packing motifs. Herein, multicolor emission is governed by tailoring the geometries of π-π dimers. Using perylene (PE) as a planar π-fluorophore, we strategically design a compound, 3-(4-(1,2,2-triphenylvinyl)phenyl)perylene (pTPE-PE), which integrates a tetraphenyl ethylene (TPE) substituent with multiple rotatable phenyl rings to modulate the PE-based π-π dimer formation. On the one hand, pTPE-PE crystallization produces four polymorphs exhibiting green, yellow, orange, and red emission color, which are static presentations of the dimer model. This static multicolor emission is directly linked to π-π interactions within the dimers: a smaller interplanar distance and a larger overlap ratio between π-π PE units result in more strengthened interactions and more red-shifted emission. On the other hand, the observed multicolor transitions under pressure (yellow → orange → red) via dimer compression and thermal stimuli (sky-blue → green → orange) through dimer (dis)assembly provide dynamic presentation of the dimer model. Consequently, polymorphism/piezochromism/thermochromism not only provides direct experimental evidence for exciton modulation from the perspective of the simplest supramolecular dimer model, but also offers insights for designing intelligent optical materials.
