Recyclable polyisobutylene (PIB)-bound organic photoredox catalyst catalyzed polymerization reactions

Abstract

This describes the preparation of a recyclable organo photoredox catalyst that efficiently carries out light-mediated radical polymerizations of acrylates. This PIB-bound 10-phenylphenothiazine organic photoredox catalyst can be easily separated from the polymer product and reused via a facile biphasic separation process for 3 cycles with no significant loss of catalytic activity.
