제목 Topology Transformation toward Cyclic, Figure-Eight-Shaped, and Cross-Linked Polymers Based on Dynamic Covalent Chemistry
초록 Topology transformations of polymer architectures via dynamic covalent chemistry have attracted considerable attention in recent decades. However, topology transformations to produce cyclic topologies remain challenging. In this study, various cyclic polymers, namely, cyclic polymers and figure-eight-shaped polymers, were synthesized based on the dynamic behavior of the bis(2,2,6,6-tetramethylpiperidin-1-yl)disulfide (BiTEMPS) linkage. The simplicity and substrate versatility of this procedure are demonstrated via the highly efficient gramscale synthesis of cyclic and figure-eight-shaped polymers. Moreover, we describe the topology transformation of the obtained cyclic and/or figure-eight-shaped polymers into cross-linked polymers with precisely controlled physical properties by using their cyclic or figure-eight topology and the dynamic nature of the BiTEMPS units in their structures.
