Abstract
The vat-based 3D printing of a chemical reactor with flow-meter geometry from an isocyanate-functionalized acrylate monomer followed by post-processing with amino-functionalized photocatalysts is described. This approach results in solvent- and air-stable flow photochemical reactors with UV-A transparent windows that can be applied for photooxygenation and photo redox catalysis.
