Description:Research Seminar Abstract\n\nPhotoinduced organocatalyzed atom 
 transfer radical polymerization (O-ATRP) is a new polymerization methodolo
 gy that relies on excitation of a photocatalyst to operate an oxidative qu
 enching photoredox catalytic cycle and produce well-defined polymers. Cent
 ral to the development of O-ATRP has been the design and study of strongly
  reducing organic photocatalysts\, particularly in the context of methacry
 late monomer polymerizations. However\, as a burgeoning methodology\, the 
 full scope of O-ATRP has not yet been established. In this presentation\, 
 I discuss how features of the oxidative quenching mechanistic cycle have i
 nspired the expansion and utility of O-ATRP\, including manipulation of th
 e photoexcitation process through adaptation to continuous flow reactors\,
  the effect of multifunctional initiators for star polymer synthesis on ac
 tivation\, and directed design of improved catalysts for polymerization of
  monomers with high rates for polymerization propagation. 4:00 pm
