Cyclic polymers have attracted scientific and practical attention due to their unique set of properties arising from the restricted chain conformation and the lack of end groups. The synthesis of discrete cyclic polymers and block copolymers was recently reported using the combination of the iterative convergent method and the intramolecular cyclization. The studies on cyclic polymers without trace amounts of linear contaminants were performed to provide fundamental insights into the chemical and physical properties. In addition, polymer catenanes, composed of interlocked cyclic polymers, were prepared by the template threading approach. Using the cross-convergent method, functional monomers were precisely placed into polymer chains to make use of intermolecular interations as a binding force. The binding interactions induced a linear chain to thread through cyclic polymer, leading to the efficient preparation of polymer catenanes. |
