Anthraquinones (AQs) constitute the largest group of natural pigments, are commonly found in dyes, and are widely used in the textile industry due their photostability. They combine high absorptivity in the visible region with high excited‐state reduction potentials, making them effective acceptors of electrons and hydrogen atoms. AQs can be employed as organic catalysts in photooxidation reactions as well to produce reactive oxygen species (ROS). All these methods feature green chemistry aspects such as avoiding heavy metals, reducing waste, using inexpensive reagents, employing environmentally low‐impact solvents, and oxidizing with O₂. This review covers the application of AQs in photoredox catalysis.

蒽醌：多功能有机光催化剂

蒽醌（AQs）构成了最大的一组天然颜料，通常在染料中发现，由于其光稳定性而广泛用于纺织工业。它们将可见光区的高吸收率与高激发态还原电势相结合，使其成为电子和氢原子的有效受体。AQ还可在光氧化反应中用作有机催化剂，以产生活性氧（ROS）。所有这些方法都具有绿色化学方面的特点，例如避免重金属，减少浪费，使用廉价的试剂，使用对环境影响较小的溶剂以及用O ₂氧化。这篇综述涵盖了AQ在光氧化还原催化中的应用。
