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

Amphiphilic aluminum(III) porphyrin (AlC7P) has been designed, and its aggregation-induced photophysics has been reported. The meso-positions of the aluminum(III) porphyrin are functionalized with a heptyl chain (C7), while the central porphyrin features an axial OH group on the Al center. The hydrophilic (OH) and hydrophobic (C7) properties combined with the Lewis acid (Al center) and Lewis base (OH group) functionality to facilitate the formation of aggregation through self-assembly. Spectroscopic studies indicate that aggregation can be modulated by solvent and temperature; it is more pronounced in long-chain hydrocarbon solvents, such as hexanes and n-heptane, and is favored at lower temperatures. At low temperature conditions, the aggregated molecules manifest low fluorescence yields, whereas at higher temperatures, the self-assembly breaks down to exhibit high fluorescence yields. This temperature-dependent aggregation-induced photophysical behavior observed in hexanes makes this porphyrin ideal for a luminescent molecular thermometer.
