Organocatalyzed Atom Transfer Radical Polymerization (O-ATRP) Using a Super-Reducing Photoredox Catalyst.

ABSTRACT: The development of highly reducing photoredox catalysts (PCs) has brought forth new approaches to activating strong chemical bonds for small molecule and polymer synthesis. Organocatalyzed atom transfer radical polymerization (O-ATRP) is a polymerization methodology that uses organic PCs for the synthesis of well-defined polymers proceeding through a reversible-deactivation mechanism. However, the reaction scope of O-ATRP is confined to initiators and dormant polymer states that can be reduced by a PC. Herein, we report an O-ATRP system using a super-reducing PC to expand the capability of O-ATRP to monomers (such as styrene (St) and vinylcarbazole (VCz)) and initiators (including aromatic halides and pseudo-halides) that are challenging with most O-ATRP systems. This system provides contr
