The employment of light and/or electricity–alternatively to conventional thermal energy–
unlocks new reactivity paradigms as tools for chemical substrate activations. This leads to …

In recent years, with the development of organic synthetic chemistry, a variety of organic
synthetic methods have been discovered and applied in practical production …

Photoredox catalysis typically relies on the use of single chromophores, whereas strategies,
in which two different light absorbers are combined, are rare. In photosystems I and II of …

Photoredox catalysis (PRC) has gained enormous and wide-ranging interest in recent years
but has also been subject to significant mechanistic uncertainty, even controversy. To …

Electron‐deficient acridones and in situ generated acridinium salts are reported as potent,
closed‐shell photooxidants that undergo surprising mechanisms. When bridging acyclic …

The open-shell catalytically active species, like radical cations or radical anions, generated
by one-electron transfer of precatalysts are widely used in energy-consuming redox …

The two‐electron reduced forms of perylene diimides (PDIs) are luminescent closed‐shell
species whose photochemical properties seem underexplored. Our proof‐of‐concept study …

Anions are the reduced form of precatalysts that are a special type of photoredox catalyst,
unlike traditional iridium or ruthenium complexes. Among them, radical anions often have …

Single‐electron transfer (SET) plays a critical role in many chemical processes, from organic
synthesis to environmental remediation. However, the selective reduction of inert substrates …

Photocatalysis is a powerful tool to assemble diverse chemical scaffolds, yet a bottleneck on
its further development is the understanding of the multitude of possible pathways when …
