Unraveling Photocatalytic Mechanism and Selectivity in PET-RAFT Polymerization

Seal, Prasenjit; Xu, Jiangtao; De Luca, Sergio; Boyer, Cyrille; Smith, Sean


The photoredox catalysts pheophorbide a (PheoA) and zinc tetraphenylporphine (ZnTPP) under illumination display strong selectivity toward reversible addition–fragmentation chain transfer (RAFT) agents containing thiocarbonylthio groups, namely dithiobenzoates, xanthates, and trithiocarbonates. The underlying mechanism for the process—whether via energy or electron transfer from the photoexcited catalyst to RAFT agent—has remained unclear, as has the reason for the remarkable selectivity....[Show more]
