要旨

This study reports the discovery that trithiocarbonate RAFT agents can significantly reduce the amount of dissolved oxygen when irradiated with visible light (λmax ≈ 460 nm) in the presence of a sacrificial tertiary amine. By taking advantage of this effect, we conducted a series of photo-CRPs of acrylates without the requirement of pre-degassing the reaction mixtures. In these systems, the trithiocarbonate plays a triple role of photocatalyst for oxygen removal, initiator, and RAFT agent for polymerization control. We believe this robust and facile synthetic method will be beneficial for cost-effective industrial applications as well as the laboratory-scale synthesis of functional polymeric materials.
