由拓扑结构单元形成的超分子聚合物为创造新型超分子结构和功能材料开辟了新的途径。树枝化超分子聚合物（DSPs）联合收割机结合了树枝化聚合物的拓扑特征和超分子化学的动力学性质，有望用于超分子结构的形成和功能组装。这些拓扑超分子聚合物具有特征性的圆柱形状、高刚性、多价性以及固有厚度。这些结构特征使它们成为超分子组装的理想候选者。DSP可以通过非共价相互作用形成，如氢键，π-π堆积和金属配位，并分为主链，侧链和嵌段类型。这篇专题文章将总结制备均相和嵌段DSP的方法，重点是它们的超分子结构形成。特别注意的是把DSP的超分子组装的结构影响。
Supramolecular polymers formed from topological building blocks pave a new avenue for creating novel supramolecular structures and functional materials. Dendronized supramolecular polymers (DSPs) combine the topological characteristics of dendronized polymers and a dynamic nature from supramolecular chemistry, and are promising for the formation of supramolecular structures and functional assemblies. These topological supramolecular polymers have a characteristic cylindrical shape, high rigidity, multivalency, as well as inherent thickness. These structural characteristics make them ideal candidates for supramolecular assembly. DSPs can be formed through non-covalent interactions, such as hydrogen bonding, π–π stacking, and metal coordination, and classified into main-chain, side-chain and block types. This feature article will summarize methodologies for the preparation of homo- and block DSPs with a focus on their supramolecular structure formation. Particular attention is put on the structural effects of DSPs on their supramolecular assembly.
