Description:
Atom transfer radical polymerization (ATRP) has become one of the most implemented methods for polymer synthesis due to impressive control over polymer composition and associated properties. However, contamination of the polymer by the metal catalyst remains a major limitation. Organic ATRP photoredox catalysts have been sought to address this difficult challenge, but have not achieved the precision performance of metal catalysts. Here, we introduce diaryl dihydrophenazines, identified through computationally directed discovery, as a class of strongly reducing photoredox catalysts. These catalysts achieve high initiator efficiencies through activation by visible light to synthesize polymers with tunable molecular weights and low dispersities.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Theriot, Jordan C -- Lim, Chern-Hooi -- Yang, Haishen -- Ryan, Matthew D -- Musgrave, Charles B -- Miyake, Garret M -- New York, N.Y. -- Science. 2016 Mar 31. pii: aaf3935.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and Biochemistry, University of Colorado Boulder, Boulder, Colorado 80309, USA. ; Department of Chemistry and Biochemistry, University of Colorado Boulder, Boulder, Colorado 80309, USA.
