The synthesis and dynamic nature of macromolecular systems controlled by rotaxane macromolecular switches are introduced to discuss the significance of rotaxane linking of polymer chains and its topological switching. Macromolecular switches have been synthesized from macromolecular [2]rotaxanes (M2Rs) using sec-ammonium salt/crown ether couples. The successful synthesis of M2Rs possessing a single polymer axle and one crown ether wheel, constituting a key component of the macromolecular switch, has allowed us to develop various unique applications such as the development of topology-transformable polymers. Polymer topological transformations (e.g., linear-star and linear-cyclic) are achieved using rotaxane-linked polymers and rotaxane macromolecular switches. The pronounced dynamic nature of these polymer systems is sufficiently interesting to design sophisticated stimuli-responsive molecules, polymers, and materials.

由轮烷高分子开关控制的可开关聚合物材料。



介绍了轮烷大分子开关控制的大分子体系的合成和动力学性质,讨论了轮烷聚合物链连接及其拓扑转换的意义。使用仲铵盐/冠醚对从大分子[2]轮烷(M2Rs)合成了大分子开关。成功合成具有单聚合物轴和冠醚轮的M2R,构成高分子开关的关键部件,使我们能够开发各种独特的应用,例如开发拓扑可转换聚合物。使用轮烷连接的聚合物和轮烷大分子开关实现聚合物拓扑变换(例如,线性星形和线性环状)。这些聚合物系统显着的动态性质对于设计复杂的刺激响应分子、聚合物和材料来说非常有趣。
