The Right Light: De Novo Design of a Robust Modular Photochemical Reactor for Optimum Batch and Flow Chemistry

Abstract

Abstract Having identified inconsistencies when repeating literature examples of photochemical transformations and difficulties recreating experimental setups, we devised several criteria that an ideal lab‐scale reactor should achieve. Herein, we introduce a versatile photoreactor for high‐throughput screening, preparative‐scale batch reactions and continuous processing, all with a single light source. The reactor utilizes interchangeable arrays of pseudo‐monochromatic high‐power LEDs in a range of synthetically useful wavelengths, combined with excellent temperature control. Moreover, light intensity can be modulated in an accurate and straightforward manner. This system has subsequently been tested on a range of literature methodologies.
