Visible 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 کاملMacromolecular engineering by atom transfer radical polymerization.
This Perspective presents recent advances in macromolecular engineering enabled by ATRP. They include the fundamental mechanistic and synthetic features of ATRP with emphasis on various catalytic/initiation systems that use parts-per-million concentrations of Cu catalysts and can be run in environmentally friendly media, e.g., water. The roles of the major components of ATRP--monomers, initiato...
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...

متن کاملThermosensitive Nanocables Prepared by Surface-Initiated Atom Transfer Radical Polymerization
Thermosensitive nanocables consisting of Au nanowire cores and poly(N-isopropylacrylamide) sheaths (denoted as Au/PNIPAAm) were synthesized by surface-initiated atom transfer radical polymerization (SI-ATRP). The formation of PNIPAAm sheath was verified by Fourier transform infrared (FTIR) and hydrogen nuclear magnetic resonance ((1)H NMR) spectroscopy. Transmission electron microscope (TEM) re...
