Membrane reactors accelerate polymer photosensitizer-based singlet oxygen reactions

Polymer photosensitizers have gained a growing interest as singlet oxygen (1O2) generators. Although they provide route to sustainable chemistry, their efficiency in bulk reactions is restricted by limited supply and short lifetime. Herein, we report membrane reactors that support range of organic using 1O2 generated from polymer photosensitizers. The porous nature the support, nylon fabric functionalized with poly(fluorenthiophen thiadiazothiophen) (PFOTTzT), allows highly efficient trapping thin reagents close proximity source. We demonstrate oxidation are accelerated 10 – 100 folds, polymerization rapidly initiated reach nearly 2-fold increase degree polymerization. method compatible solvents upon protection polymeric layer polytetrafluoroethylene (PTFE) prevents solvent transport but diffusion through. Summarizing, our sustainable, low-cost, robust-in-use overcome current limitations involving show strong potential for green industrial use.
