Photoorganocatalysis has been recognised by the organic chemistry community as an important part of photochemistry and catalysis. In general, aromatic ketones constitute key players in this type of catalysis as they are involved in a plethora of examples in the literature. Among the various aromatic ketones, thioxanthone (TX) seems to play a unique role in photochemistry. In comparison with other aromatic ketones, TX has a high triplet energy and a relatively long triplet lifetime, while it has the ability to participate successfully in merger reactions with metal complexes. In this review, we will discuss the photophysical properties of this small organic molecule, as well as the numerous examples of photochemical reactions, where it is employed as a mediator and more specifically in polymerisation reactions, and organic transformations.
光有机催化已被有机化学界公认为光化学和催化的重要组成部分。一般来说，芳香酮作为此类催化中的关键反应物，在文献中有大量的例子。在各种芳香酮中，硫杂蒽酮 (TX) 在光化学中似乎起着独特的作用。与其他芳香酮相比，TX 具有较高的三重态能量和相对较长的三重态寿命，同时它还有能力与金属配合物成功地参与合并反应。在这篇综述中，我们将讨论这个小分子的光物理性质，以及它作为介体在许多光化学反应中的应用实例，特别是在聚合反应和有机转化中。
