Metal-free atom transfer radical polymerization with ppm catalyst loading under sunlight

Nature Communications, 2021
Organocatalytic atom transfer radical polymerization (O-ATRP) is attractive due to its metal-free nature but catalysts are rarely applied at a low loading. Here the authors introduce a catalyst design logic based on heteroatom-doping of polycyclic arenes,

Electrochemical Investigation of Iron-Catalyzed Atom Transfer Radical Polymerization

Molecules, 2022
Use of iron-based catalysts in atom transfer radical polymerization (ATRP) is very interesting because of the abundance of the metal and its biocompatibility. Although the mechanism of action is not well understood yet, iron halide salts are usually used
