Distinct mechanochromic and piezochromic behaviors of thermally activated delayed fluorescence 4CzTPN crystal.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Incorporating mechano-luminescence into thermally activated delayed fluorescence (TADF) molecules represents a promising strategy for developing multifunctional mechanoluminescent materials. However, the controllable utilization of the versatile properties inherent in TADF molecules remains challenging due to the inherent difficulties in system design. Herein, we investigate the pressure modulation of the photophysical properties of 2,3,5,6-tetrakis(carbazol-9-yl)-1,4-dicyanobenzene (4CzTPN), a representative TADF emitter, through in situ high-pressure photoluminescence (PL), time-resolved PL, UV-visible spectra and infrared spectroscopy. The different mechanisms of a blue shift by grinding crystals and of a red shift under hydrostatic pressure are fully investigated. High-pressure time-resolved PL measurements show that the short fluorescence lifetime decreases and the lifetime of delayed fluorescence disappears beyond 3.0 GPa. Infrared spectra indicate the pattern of relative intensity for the infrared absorption peak of ν(C-H) transform significantly when the pressure is greater than 3.0 GPa, which would be the cause of the disappearance of delayed fluorescence. This study enriches the insights into mechanochromic and multifunctional materials.
