Abstract

This paper focuses on one of the next directions in the evolution of reversible addition-fragmentation (RAFT) polymerization, namely, progress towards the synthesis of discrete or uniform, sequence-defined (co)polymers. Following a brief review of RAFT-single unit monomer insertion (RAFT-SUMI), we describe recent developments in the field. We point to difficulties in achieving consecutive RAFT-SUMI and report two strategies for overcoming the issue of initiator-derived by-products. We show that the selection of RAFT agent is critical in selective RAFT-SUMI of N,N-dimethylacrylamide (DMAm) into a trithiocarbonate in aqueous solution. Finally we recount on the use of photoRAFT- or PET-RAFT-SUMI in the high yield synthesis of discrete oligomers comprising two or more consecutive SUMI steps.
