Intrigued by natural responsive systems based on a combination of macromolecules and non-covalent interactions, polymer scientists have mimicked such systems by the formation of supramolecular polymers based on ionic interaction, hydrogen bonding and metal coordination. In recent years, the focus has shifted from rather simple non-directional and self-complementary interactions to the use of asymmetrical directional supramolecular interactions that allow the formation of complex responsive macromolecular architectures such as block copolymers, star-shaped polymers and graft copolymers. This feature article covers these recent developments on the use of asymmetrical supramolecular interactions in polymer science. Special attention is given to the formation of complex macromolecular architectures using directional supramolecular interactions. In addition, the responsiveness of the resulting macromolecular systems is discussed based on the assembly and/or disassembly that can be triggered by changes in external conditions.
受基于大分子与非共价相互作用结合的天然响应系统的启发，聚合物科学家通过基于离子相互作用、氢键和金属配位形成超分子聚合物来模拟此类系统。近年来，研究重点已从相当简单的非定向和自互补相互作用转向使用不对称定向超分子相互作用，这种相互作用能够形成复杂的响应性大分子结构，如嵌段共聚物、星形聚合物和接枝共聚物。这篇专题文章涵盖了聚合物科学中使用不对称超分子相互作用的这些最新进展。特别关注了利用定向超分子相互作用形成复杂大分子结构的情况。此外，基于可由外部条件变化触发其组装和/或拆卸的情况，对所得大分子系统的响应性进行了讨论。
