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

Achieving rapid modulation of molecular luminescence under external stimuli remains a significant challenge in organic luminescent materials. Herein, we present a radical-mediated approach to achieve dynamic fluorescence switching. A series of benzil derivatives (BS, BZ, BD, and BQ) exhibit rapid transitions from nearly non-luminescent states to highly fluorescent states under continuous ultraviolet (UV) irradiation in solution. Notably, the absolute photoluminescence quantum yield of BS solution increased 41-fold, from 1.26% to 51.09%, after 330 s of 365 nm UV exposure. Mechanistic investigations reveal that this unique luminescence enhancement originates from UV-induced generation of aromatic carbonyl radicals. In general, molecules in solution undergo photodegradation with increasing irradiation time, resulting in a decrease in luminescence intensity. In contrast, we report a molecule whose luminescence intensity increases with increasing irradiation time, which is very rare. This work not only advances the mechanistic understanding of stimuli-responsive luminescence but also opens a new avenue for designing smart organic materials with tailored optoelectronic functionalities.
