Photochemical transformations are considered as an important way to effectively utilize luminous energy for the realization of chemical reactions, and microreactor technology provides a strong platform for improving its process efficiency. In the introduction section, firstly it is pointed out that microreactors have many obvious advantages on various aspects such as distribution of light intensity, process scale-up and utilization efficiency of luminous energy, compared with conventional batch photoreactors, and they can intensify photochemical reaction processes efficiently. Afterwards, the basic characteristics of photochemistry and photochemical microreaction technology are introduced, and the design and construction of photomicroreactors and its applications on the fields of organic synthesis, polymerization, etc., are systematically reviewed. Then photochemical microreaction systems with automation control and its applications are elaborately introduced. In particular, the progress on the photochemical synthesis in microreactors under ultraviolet or visible light irradiation and its process scale-up are highlighted. Finally, the progress in the photochemical microreactor technology is summarized, and its development trend is prospected.
