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

The efficiency of covalent organic framework (COF)-based photocatalysts depends on their electron transfer behavior, which can be rationalized in terms of conjugation effects and induction effects. While conjugation effects have been widely explored in COF-based photocatalysts, induction effects have largely been ignored despite being important to overall photocatalytic activity. Herein, a new isoreticular series of ordered COFs was rationally designed to determine the relative importance of conjugation and induction effects in promoting photocatalytic activity. Systematic component modulation revealed the importance of a balance of conjugation and induction effects in achieving optimum catalytic performance in COF-based photocatalysts. Our study shows that (i) induction effects lead to electrons accumulating in specific positions of COFs, while (ii) p-π and π-π conjugation enables accurate electron transfer to the electron-rich active sites, thereby facilitating photogenerated electron-hole separation and transport and boosting photocatalytic activity. One of our developed COFs (COF-3S) displayed excellent photocatalytic uranium extraction performance in contaminated groundwater and seawater. These results establish that both induction and conjugation effects affect the photocatalytic activity of COFs, which is expected to provide new insight into the rational design of high-performance COF-based photocatalysts.
