Journal ArticleDOI
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
Controlled radical polymerization of acrylates regulated by visible light
Nicolas J. Treat,Brett P. Fors,John W. Kramer,Matthew D. Christianson,Chien-Yang Chiu,Javier Read de Alaniz,Craig J. Hawker +6 more
TL;DR: In this article, the same authors used an Ir-catalyzed visible light mediated process leading to well defined homo-, random, and block copolymers, which could be efficiently activated and deactivated using light while maintaining a linear increase in molecular weight with conversion and first order kinetics.
Journal ArticleDOI
A highly reducing metal-free photoredox catalyst: design and application in radical dehalogenations
Emre H. Discekici,Nicolas J. Treat,Saemi O. Poelma,Kaila M. Mattson,Zachary M. Hudson,Yingdong Luo,Craig J. Hawker,Javier Read de Alaniz +7 more
TL;DR: The use of 10-phenylphenothiazine (PTH) is reported as an inexpensive, highly reducing metal-free photocatalyst for the reduction of carbon-halogen bonds via the trapping ofcarbon-centered radical intermediates with a mild hydrogen atom donor.
Journal ArticleDOI
Tunable Visible and Near Infrared Photoswitches
James R. Hemmer,Saemi O. Poelma,Nicolas J. Treat,Zachariah A. Page,Neil D. Dolinski,Yvonne J. Diaz,Warren Tomlinson,Kyle D. Clark,Joseph P. Hooper,Craig J. Hawker,Javier Read de Alaniz +10 more
TL;DR: A class of tunable visible and near-infrared donor-acceptor Stenhouse adduct (DASA) photoswitches were efficiently synthesized in two to four steps from commercially available starting materials with minimal purification, yielding fully transparent, colorless solutions and films.
Journal ArticleDOI
