Metal-Free Atom Transfer Radical Polymerization
Nicolas J. Treat,Hazel Sprafke,John W. Kramer,Paul G. Clark,Bryan E. Barton,Javier Read de Alaniz,Brett P. Fors,Craig J. Hawker,Craig J. Hawker +8 more
TL;DR: A metal-free ATRP process, mediated by light and catalyzed by an organic-based photoredox catalyst, is reported that resulted in block copolymer formation was facile and could be combined with other controlled radical processes leading to structural and synthetic versatility.
Journal ArticleDOI

Clark,Javier Read de Alaniz,Javier Read de Alaniz,Craig J. Hawker,Craig J. Hawker +23 more
TL;DR: In this paper, an operationally simple, metal-free surface-initiated atom transfer radical polymerization (SI-ATRP) based on visible-light mediation is reported.
Journal ArticleDOI
Switching and Extension of a [c2]Daisy-Chain Dimer Polymer
TL;DR: The synthesis of a [c2]daisy-chain dimer via ruthenium-catalyzed ring-closing olefin metathesis using alkyne-azide "click" reaction is reported, confirming the interlocked nature of the structure.
Journal ArticleDOI
A Versatile and Scalable Strategy to Discrete Oligomers
Jimmy Lawrence,Sang-Ho Lee,Allison Abdilla,Mitchell D. Nothling,Mitchell D. Nothling,Jing M. Ren,Abigail S. Knight,Carolin Fleischmann,Youli Li,Austin S. Abrams,Bernhard V. K. J. Schmidt,Michael C. Hawker,Luke A. Connal,Alaina J. McGrath,Paul G. Clark,Will R. Gutekunst,Craig J. Hawker +16 more
TL;DR: A versatile strategy is reported for the multigram synthesis of discrete oligomers from commercially available monomer families, e.g., acrylates, styrenics, and siloxanes, with the identification of reproducible procedures for the separation of oligomer mixtures using automated flash chromatography systems.
Journal ArticleDOI
Chemoselective Radical Dehalogenation and C–C Bond Formation on Aryl Halide Substrates Using Organic Photoredox Catalysts
Saemi O. Poelma,G. Leslie Burnett,Emre H. Discekici,Kaila M. Mattson,Nicolas J. Treat,Yingdong Luo,Zachary M. Hudson,Shelby L. Shankel,Paul G. Clark,John W. Kramer,Craig J. Hawker,Javier Read de Alaniz +11 more
TL;DR: The ability to tune the reduction potential of metal-free phenothiazine-based photoredox catalysts is reported and the application of these catalysts for chemoselective carbon-halogen bond activation to achieve C-C cross-coupling reactions as well as reductive dehalogenations is demonstrated.
