Perylene as an Organic Photocatalyst for the Radical Polymerization of Functionalized Vinyl Monomers through Oxidative Quenching with Alkyl Bromides and Visible Light
The generation of carbon-centered radicals from alkyl bromides through an oxidative quenching pathway using perylene as an organic visible-light photocatalyst is described. This methodology is used to initiate the radical polymerization of methyl methacrylate and other functionalized vinyl monomers. The polymers possess bromide chain-end groups that can be used to reinitiate polymerization to p...
متن کاملVisible Light-Induced Atom Transfer Radical Polymerization for Macromolecular Syntheses
Visible light-induced atom transfer radical polymerization (ATRP) of vinyl monomers are examined by using various photocatalysts systems including Type I and Type II photoinitiators, dyes, dimanganese decacarbonyl and semiconducting photocatalysts. The influence of various experimental parameters on the polymerization such as type of light sources and photocatalyts, and concentration of metal c...

متن کاملpoly(vinyl acetate)-based block copolymer/clay nanocomposites prepared by in situ atom transfer radical polymerization
atom transfer radical polymerization of styrene (st) and methyl methacrylate (mma) was performed at 90oc in the absence and presence of nanoclay (cloisite 30b). trichloromethyl-terminated poly(vinyl acetate) telomerand cucl/ pmdeta were used as a macroinitiator and catalyst system, respectively. the experimental results showed that the atom transfer radical polymerization of st and mma in the a...
متن کاملMetal-free atom transfer radical polymerization.
Overcoming the challenge of metal contamination in traditional ATRP systems, a metal-free ATRP process, mediated by light and catalyzed by an organic-based photoredox catalyst, is reported. Polymerization of vinyl monomers are efficiently activated and deactivated with light leading to excellent control over the molecular weight, polydispersity, and chain ends of the resulting polymers. Signifi...
