光化学反应不仅利用可再生的光能作为能源, 而且可以发现一些传统热化学反应难以实现的反应历程, 成为近年来合成化学领域研究的热点. 光化学反应往往需要加入光催化剂吸收光子的能量, 进而与底物发生电子转移或能量转移来完成后续化学转化, 因此设计发展廉价易得、转化效率高和稳定性好的光敏剂是有机光化学反应的一项重要研究内容, 其中三芳胺在光催化反应中逐渐引起关注. 此综述对近年来通过三芳胺介导/催化的光化学反应研究进展进行了归纳总结, 阐述了可见光条件下三芳胺促进的芳烃碳氢键官能团化反应、烯烃官能团化反应和环加成反应. 最后对三芳胺在光催化反应中的应用进行了总结与展望.

Photochemical reactions not only utilize renewable light energy as a source, but also can uncover reaction pathways that are difficult to achieve through traditional thermochemical reactions, making them an emerging research topic in the field of synthetic chemistry in recent years. Photochemical reactions often require the addition of a photocatalyst to absorb the energy of photons, and then undergo electron transfer or energy transfer with the substrate to complete the subsequent chemical transformation. Therefore, the design and development of inexpensive, easily accessible, high-efficiency, and stable photosensitizers is an important research topic in organic photochemical reactions. In this context, triarylamine has gradually attracted increasing attention in photocatalytic reactions. The recent research progress on photochemical reactions mediated/catalyzed by triarylamine is summarized. The content includes triarylamine-promoted functionalization of aromatic C—H bonds, olefin functionalization reactions, and cycloaddition reactions under visible light irradiation. Finally, the application of triarylamine in photocatalytic reactions is summarized and prospected.
