Organic Photocatalysts Applied to Metal-Free Atom Transfer Radical Polymerization
Metal-free atom transfer radical polymerization (ATRP) mediated by organic photocatalysts has been one of the attracting topics.1) For instance, 10-phenylphenothiazine,2) perylene,3) and fluorescein4) and an amine as an electron donor, has been reported as organic photocatalysts. In addition, attempts to develop novel organic photocatalysts are ongoing in order to expand applicable light sources or to enable more precise polymerization control.1,5) Metal-free ATRP is anticipated in the application of electronic materials or biomaterials since it requires no copper catalyst when compared to the conventional ATRP.
