Room-temperature phosphorescence and anomalous piezochromism in molecular crystals enabled by iodine atomic orbital sharing.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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
Controlling room-temperature phosphorescence (RTP) in organic materials through external stimuli is crucial for elucidating RTP mechanisms and engineering stimuli-responsive materials for various applications. However, compared to fluorescent materials, regulating RTP presents greater challenges due to its intricate photophysical processes, particularly in the quest for RTP materials with desirable stimulus-responsive properties. Here we show that when the interactions of iodine with neighboring molecules in 1,4-diiodotetrafluorobenzene (1,4-DITFB) crystals are tuned by pressure, exotic emission behaviors emerge. These emissions exhibit anomalous blue-shifted characteristics and enhanced intensities upon compression, accompanied by prolonged lifetimes. Notably, such piezochromic luminescence responses are impeded through a co-crystallization strategy that hinders iodine-iodine interactions. We further reveal that the observed anomalous emissions related to the unique state of iodine by providing additional orbitals shared with surrounding molecules. Our findings not only open pathways for designing tailored stimuli-responsive luminescent materials but also offer valuable insights into the underlying mechanisms governing organic RTP emitters.
