Layer Sliding-Induced Fluorescence Changes in a Flexible Hydrogen-Bonded Organic Framework.

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
Flexible hydrogen-bonded organic frameworks (HOFs) capable of changing their fluorescence properties upon structural transformation have gained much attention, while their design strategies have not been established. Herein, we demonstrate that sliding of the robust hydrogen-bonded 2D layers can induce dynamic emission color changes of HOFs. Layered HOF CP-tBPy-1, which is composed of tert-butylpyrene derivative with four carboxyphenyl groups (CP-tBPy), transformed to another crystalline form, CP-tBPy-2, upon release of guest solvent molecules. Single-crystal X-ray diffraction analysis revealed that the sliding of the layers changed the pyrene cores from monomeric to dimeric species, giving rise to fluorescence color changes from blue to green. Fluorescence spectroscopy and single-crystals microscopy disclosed details of the photobehaviors of these HOFs. These results are the first example of fluorescence changes of HOFs due to sliding of hydrogen-bonded 2D network layers, providing a new design strategy to construct functional fluorescent porous materials.
