Better Together: Photoredox/Copper Dual Catalysis in Atom Transfer Radical Polymerization

Angewandte Chemie, Volume 137, Issue 2, January 10, 2025.
A combination of Cu‐ATRP catalysis with photocatalysts (PCs) that absorb visible and/or NIR light exhibits synergistic action at the ppm/ppb concentration level. It leads to very well‐defined polymers with rates depending on the amount and quantum efficiency of PC but controlled polymer architecture defined by the Cu‐catalysts.
