| Summary: | Reversible Addition-Fragmentation Chain Transfer (RAFT) step-growth polymerization is an emerging method that synergistically combines the benefits of RAFT polymerization (functional group and user-friendly nature) and step-growth polymerization (versatility of the polymer backbone). This new polymerization method is generally achieved by using bifunctional reagents of monomer and Chain Transfer Agent (CTA), that efficiently yield Single Monomer Unit Insertion (SUMI) adducts under stoichiometrically balanced conditions. This review covers a brief history of the RAFT-SUMI process and its transformation into RAFT step-growth polymerization, followed by a comprehensive discussion of various RAFT step-growth systems. Furthermore, characterizing the molecular weight evolution of step-growth polymerization is elaborated based on the Flory model. Finally, a formula is introduced to describe the efficiency of the RAFT-SUMI process, assuming rapid chain transfer equilibrium. Examples of reported RAFT step-growth and SUMI systems are then categorized based on the driving force.

| Bibliography: | Wei You received his BS degree in Polymer Chemistry from the University of Science and Technology of China in 1999. He then obtained his PhD in 2004 under the guidance of Professor Luping Yu at the University of Chicago. After finishing his postdoctoral training at Stanford University in 2006 with Professor Zhenan Bao, he joined the University of North Carolina at Chapel Hill as an Assistant Professor in Chemistry in July 2006. He was promoted to the rank of Associate Professor in 2012 and then Full Professor in 2017. He has published over 180 papers in three main areas: conjugated polymers for optoelectronics (particularly polymer solar cells), new polymerization methodologies and their applications, and organic/inorganic hybrid 2D perovskites. He was an Associate Editor for Polymer Chemistry (RSC) (2013-2022) and has been serving as Specialty Chief Editor for Optoelectronic Materials, Frontiers in Electronic Materials since July 2020. He also served on the advisory board for Macromolecules (ACS) and ACS Applied Energy Materials (ACS). He is a Fellow of Royal Society of Chemistry (FRSC) (2017), and is one of the "World Highly Cited Researchers" as determined by the Web of Science Group (2019-2022). Jiajia Li received his BS degree in Chemistry from Soochow University, Suzhou, China, in 2015. He completed his PhD in Polymer Chemistry at Soochow University (2020) under the guidance of Prof. Jian Zhu. He was a joint PhD student at the University of Warwick under the supervision of Prof. Sébastien Perrier from 2019 to 2020. After finishing his postdoctoral studies at Soochow University with Prof. Jian Zhu from 2020 to 2022, he moved to the University of North Carolina at Chapel Hill to work with Prof. Wei You. His current interest focuses on reversible deactivation radical polymerization, living cationic polymerization and photopolymerization-based 3D printing. Joji Tanaka completed his MChem at the University of Warwick in 2013, working under Prof. David M. Haddleton for his final year thesis. At the same university, he obtained his PhD under the guidance of Prof. Sébastien Perrier and Dr Paul Wilson in 2018. Currently, he works at the University of North Carolina (UNC) at Chapel Hill with Prof. Wei You. He was responsible for writing the NSF grant titled "RAFT Step-Growth Polymerization" (CHE-2108670), which was successfully funded in 2021 and has since led the RAFT step-growth team in the You group. His research focuses on designing novel methodologies via the RAFT process, mathematical modelling, and alternative characterization strategies. Samantha Marie Clouthier obtained her BSc from Cornell University in 2021. She is currently a graduate student pursuing her PhD at the University of North Carolina at Chapel Hill under the supervision of Prof. Wei You. She is a 2023 recipient of the National Science Foundation (NSF) Graduate Research Fellowship Program (GRFP). Her research is focused on photo-mediated RAFT step-growth polymerization.
