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

Conjugated covalent organic frameworks (COFs) have emerged as a promising class of semiconducting heterogeneous photocatalysts. Precise control of the conjugation within their framework is pivotal for tuning electronic structures and optimizing catalytic performance, yet conventional approaches for linker extension face significant synthetic limitations. We report in this work a multicomponent reaction strategy that enables stepwise tuning of the conjugation of COFs through linkage conversion, where imine linkages are sequentially transformed into tetrahydrophenanthridine and further into phenanthridine units. The progressively extended conjugation results in a lower bandgap and reduced exciton binding energy, thereby promoting light harvesting and subsequent free charge carrier generation and utilization. Among the COFs bearing different linkages, the phenanthridine-linked COF exhibits superior efficiency in photocatalytic activation of molecular oxygen for a variety of chemical transformations, including hydrogen peroxide generation, thioether oxidation, and benzimidazole synthesis under mild conditions.
