Self-Catalyzing Photoredox Polymerization For Recyclable Polymer Catalysts Dagger

We describe a self-catalyzing photoredox polymerization system for the modular generation of macromolecular photocatalysts. Specifically, we designed a photoactive eosin Y-derived monomer that can induce photoelectron/energy transfer, while simultaneously partaking in reversible addition-fragmentation chain transfer polymerization as a monomer, affording polymer catalysts with tunable eosin Y incorporations.
