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

Tuning of photophysical characteristics of small molecule fluorophores by simple synthetic method is desired but possesses its own challenges. We are reporting here an easy-to-achieve synthetic strategy to tune N-H maleimide-based fluorescent small molecules 2a-c to achieve large Stokes shifted solvatochromism and aggregation induced emission (AIE) via. π-surface extension. Fluorophore 2a-c exhibit broad solvatochromic emission range from blue to yellow (458 to 568 nm) due to intramolecular charge transfer with incremental large Stokes shift (110 nm to 192 nm) in nonpolar to polar solvent. The introduction of the phenyl ring affects both the electronic conjugation and the facile aggregation in the bad solvent. Along with synthesis, thermal stability and detailed photophysical study of the synthesized fluorophores and study of AIE in the THF/water mixture of a representative probe (2c) is presented. Moreover, the experimental results are well supported by the DFT study.
