Synthetic organic photochemistry has been intensively carried out in the 20^th century and paved the way to the preparation of complex organic molecules, which were not yet accessible via thermal chemistry. Several photochemical synthesis routes have found their way into industrial applications for the production of everyday commodities, but photochemistry was still underutilized until recently as a synthesis method in organic chemistry. With the advent of novel photocatalytic and photophysical concepts for the use of high power visible light, the research field of synthetic organic photochemistry has evolved to become a vivid and highly recognized technique in the last years. Fortunately, continuous flow technology has also become an increasingly accepted tool and has proved to be an excellent key player for the advancement of photochemistry in academic and industrial research settings. This Review provides an overview on the recent developments of continuous flow photoreactors and their application to photochemical syntheses under mild and defined process conditions.

流动光化学反应器技术概念

合成有机光化学已在20^世纪进行了深入研究世纪，为制备复杂的有机分子铺平了道路，这些分子尚无法通过热化学方法获得。几种光化学合成路线已进入工业生产日常用品的途径，但是直到最近，光化学仍未得到充分利用，成为有机化学中的一种合成方法。随着用于高功率可见光的新型光催化和光物理概念的出现，合成有机光化学的研究领域在过去几年中已发展成为一种生动且受到高度认可的技术。幸运的是，连续流技术也已成为越来越被人们接受的工具，并被证明是在学术和工业研究环境中促进光化学发展的出色关键角色。
