摘要

We introduce a device that allows programmable, automated changes of the irradiation wavelength and intensity for use with a continuous-flow photoreactor. Combined with parallel chromatographic analysis, the set-up enables systematic screening of photoreactions in a remarkably short time frame. This is demonstrated by investigating the photoconversion of an arylazo sulfone under different reaction conditions, with and without the use of an additive. Data obtained from a series of systematic wavelength screenings at defined irradiation intensity reveal a previously unknown intermediate and disclose a new, wavelength-dependent reaction pathway. Our study shows how systematic screening of the wavelength and irradiation intensity can contribute to the fundamental understanding of photochemical reactions.

Reaction Chemistry & Engineering is an interdisciplinary journal reporting cutting-edge research focused on enhancing the understanding and efficiency of reactions. Reaction engineering leverages the interface where fundamental molecular chemistry meets chemical engineering and technology. Challenges in chemistry can be overcome by the application of new technologies, while engineers may find improved solutions for process development from the latest developments in reaction chemistry. Reaction Chemistry & Engineering is a unique forum for researchers whose interests span the broad areas of chemical engineering and chemical sciences to come together in solving problems of importance to wider society. All papers should be written to be approachable by readers across the engineering and chemical sciences. Papers that consider multiple scales, from the laboratory up to and including plant scale, are particularly encouraged.
