Abstract

Benzo[c][1,2,5]thiadiazole (BTZ) incorporated into polymers of intrinsic microporosity (PIM) has previously been observed as a highly effective and affordable approach for photocatalyzing both visible light‐driven energy transfer and single‐electron transfer reactions. In this work, newly developed PIM‐BTZ polymers (with commercially available monomers and facile synthesis) were applied as a reactive coating on the Vortex Fluidic Device (VFD), a rapid rotating tube reactor with continuous flow capabilities. The combination of the VFD's exceptionally high mass transfer properties and the photochemical properties of the PIM‐BTZ coating was shown to synergistically accelerate organic reactions involving singlet oxygen and superoxide species, while also enabling continuous flow operation and synthesis. Compared to batch mode, the VFD achieved a dramatic increase in productivity from 15.0 mg h−1 to 126.4 mg h−1 when operated in continuous flow mode for the benchmark photooxidation of triphenylphosphine. Ultimately, the PIM‐BTZ coated VFD demonstrates robust capability as a scalable photochemical reactor.
