“…Benefiting from the tunable physicochemical properties, BCPs have found widespread applications in thermoplastic elastomers, − phase compatibilizers, , polymer electrolytes, , biomedical fields, , and so forth. Over the past decades, tremendous progress has been achieved toward BCP construction based on various living/controlled polymerization mechanisms and synthetic methodologies. − Most commonly, the sequential monomer addition or the use of a premade macroinitiator − manifested as a vigorous approach and has been applied with success to a wide array of BCPs [Figure A(a)]. However, this method involves a somewhat tedious polymerization process since it requires strict stepwise addition of different monomers.…”

A significant challenge in block copolymers (BCP) synthesis is to precisely control the block sequence and customize the composition and structure of target products from monomer mixtures. Herein, we reported a facile temperature-programmed switchable strategy based on deprotection chemistry of CO 2 , enabling precise construction of BCPs. The proposed pattern was achieved via temperature-triggered switchable terpolymerization of epoxides/five-membered cyclic carbonates/cyclic anhydrides based on the protection and deprotection chemistry of CO 2 . The chemoprotection of epoxides into cyclic carbonates and subsequent deprotection of cyclic carbonates into epoxides played a crucial role in the whole process. On the one hand, the low ring tension of five-membered cyclic carbonates resulted in vast temperature gaps between the copolymerization of epoxides/cyclic anhydrides and cyclic carbonates/cyclic anhydrides. Consequently, a facile control over the temperature-programmed parameter could direct the copolymerization cycles from epoxides/cyclic anhydrides (giving the first block at 110 °C) to cyclic carbonates/ cyclic anhydrides (yielding the second block at 180 °C), thus ensuring precise fabrication of BCPs. Moreover, this protocol was significantly effective in extending the diversity of structures and properties of blocky polyesters by selecting distinct epoxide/cyclic carbonate combinations on demand.

Controlled radical polymerization (CRP) techniques enable the preparation of diverse, chemically tailored polymers with a variety of chain architectures. Separately, light‐mediated polymerization reactions offer a number of advantages over thermal polymerizations in terms of energy efficiency, sustainability, and versatility. Recent work has combined photopolymerization and CRP techniques to advance the synthesis of polymers with nonlinear architectures, including bottlebrush polymers, star polymers, hyperbranched polymers, and cyclic polymers. These photoCRP methods offer novel routes to nonlinear polymers using mild reaction conditions. In this review, we provide an overview of photoCRP techniques for the synthesis of nonlinear polymers. We start with a discussion of photoCRP applied to the synthesis of linear polymers and discuss the underlying reaction mechanisms. Then, we discuss photoCRP applied to the synthesis of bottlebrush, star, hyperbranched, cyclic, and surface‐initiated polymer brushes. For each case, we discuss the synthetic strategy and the unique properties and characteristics of the resulting polymers, and we provide a perspective on potential future directions for research.
