Natural RAFT Polymerization: Recyclable-Catalyst-Aided, Opened-to-Air, and Sunlight-Photolyzed RAFT Polymerizations
The
successful sunlight-photolyzed reversible addition–fragmentation
chain transfer (RAFT) photopolymerization can be reversibly activated
and deactivated by irradiation with sunlight in the absence of photocatalyst
and photoinitiator. In the present work, the thiocarbonylthio compounds
(dithiobenzoate, trithiocarbonate, and xanthate) can all be employed
to carry out the polymerization under sunlight irradiation acting
as an initiator, chain transfer agent, and termination agent. Moreover,
it was demonstrated that the recyclable-catalyst-aided, opened-to-air,
and sunlight-photolyzed RAFT (ROS-RAFT) polymerizations can be successfully
carried out to fabricate precise and predictable polymers in the presence
of the recyclable magnetic semiconductor nanoparticles (NPs). The
oxygen tolerance is likely attributed to a specific interaction between
NPs and oxygen
