Switchable Polymerization Catalysts

Synergy between Electrochemical ATRP and RAFT for Polymerization at Low Copper Loading

“…Electrosynthesis and electrocatalysis are important synthetic methods that have experienced a renaissance in the past two decades . They are fundamental tools for chemical transformations, switchable catalysis, and external regulation of controlled polymerizations . By shifting the applied potential, the valence of the metal center in the catalyst complexes can be readily tuned, thus shifting the reactivity and stereoselectivity in situ.…”

Switch in Catalyst State: Single Bifunctional Bi‐state Catalyst for Two Different Reactions

“…[1] Mimicking such smart activity by artificial manmade molecules is an incessant quest for modern chemists. [2,3] Then ext generation of smart catalysts is intended to be more sophisticated by featuring switching activity and facilitating two different reactions (S1!P1 and S2!P2, Figure 1B). [2] However,a lmost all of the developed switchable catalysts show an activity-switching or stereo/chemoselectivity-switching behavior for only one catalytic reaction (S!P, Figure 1A).…”

Controlling the Ring‐Opening Polymerization Process Using External Stimuli

“…The intrinsic relation between microstructures and properties of polymers has inspired generations of researchers to develop new techniques aimed towards controlling the composition and sequence of synthetic polymers. Switchable polymerization is a rapidly evolving area that has shown great promise as a method to control the microstructures of polymers. By using external stimuli, controlling the switchable polymerization process is a powerful strategy to produce advanced and well‐defined polymeric microstructures, which could be difficult to access using traditional synthetic methods.…”
