摘要

本研究探讨了脉冲发光二极管（LED）辐照对采用六种成熟光催化剂的五种代表性光氧化反应的影响。这项研究的主要目的是更好地了解脉冲辐照在光氧化催化中的潜在影响和更广泛的范围，研究结果表明，脉冲辐照可能对反应进程产生积极、消极或可忽略不计的影响。这些影响似乎因具体反应、光氧化催化剂的特性而异，甚至会因底物的不同而不同。因此，揭示这些效应的基本机理基础既具有挑战性，又有细微差别；不过，我们的研究结果确实凸显了在光氧化反应设计过程中适当考虑本生-罗斯科定律的重要性。

Investigating the Effects of Pulsed LED Irradiation in Photoredox Catalysis: A Pilot Study

This study examines the effects of pulsed light-emitting diode (LED) irradiation across five representative photoredox reactions employing six established photocatalysts. The primary objective of this investigation was to develop a better understanding of the potential effects and broader scope of pulsed irradiation in photoredox catalysis, which the results suggest may influence reaction progress positively, negatively, or negligibly. These effects appear to vary depending on the specific reaction, the identity of the photoredox catalyst and can even differ between substrates. Accordingly, unraveling the fundamental mechanistic basis of these effects is both challenging and nuanced; however, our results do highlight the importance of properly considering the Bunsen–Roscoe Law during photoredox reaction design.

期刊介绍： Organometallics is the flagship journal of organometallic chemistry and records progress in one of the most active fields of science, bridging organic and inorganic chemistry. The journal publishes Articles, Communications, Reviews, and Tutorials (instructional overviews) that depict research on the synthesis, structure, bonding, chemical reactivity, and reaction mechanisms for a variety of applications, including catalyst design and catalytic processes; main-group, transition-metal, and lanthanide and actinide metal chemistry; synthetic aspects of polymer science and materials science; and bioorganometallic chemistry.
