从理论上讲，氧(O2)是一种理想的化学试剂，因为它的相对丰度高，环境毒性可以忽略不计。然而，在实践中，由于其基态电子构型的性质，许多涉及O2的化学反应是自旋禁止的，这极大地降低了它的反应活性，从而降低了它的应用价值。通过使用光化学和光物理方法改变O2的电子构型，可以获得更多活性形式的O2。本文重点介绍了超氧化物(O2−)和单线态氧(1O2)这两种活性氧物种(ROS)中的光-化学能转化过程，它们可以通过多种光化学方法获得，并被用于各种令人兴奋的应用中。介绍了利用光照射产生ROS的原理。然后探讨了这些方法在化学转化中的应用。图形摘要
ABSTRACT In theory, oxygen (O2) is an ideal chemical reagent because of its high relative abundance and negligible environmental toxicity. In practice however, by the nature of its ground state electronic configuration, many chemical reactions involving O2 are spin forbidden which dramatically decreases its reactivity and thus its utility in applications. More reactive forms of O2 can be achieved by changing its electronic configuration through the use of photochemical and photophysical methods. This review highlights the roll of photon-to-chemical energy conversion in two of these reactive oxygen species (ROS): superoxide (O2 −) and singlet oxygen (1O2), which can be accessed through a number of photochemical methods and used in a variety of exciting applications. The theory behind ROS is introduced as produced using light irradiation. Then applications of these methods for chemical transformations are explored. GRAPHICAL ABSTRACT
