Continuous flow photochemistry and green chemistry
The union of continuous flow processing and photochemistry has enabled the effective generation of target molecules of ever-increasing complexity and with growing selectivity. Inherent benefits of flow reactors are thereby exploited for better heat and mass transfer, containment of high energy light as well as scalability irrespective of reactor footprint. This short perspective article evaluates the advances of continuous flow photochemistry towards greener chemical synthesis and highlights remaining challenges that will need to be resolved to meet our sustainability goals.
