摘要
超分子聚合物是分子单体通过非共价键自组装形成的聚合物,鉴于其自修复性、自适应性、可降解性,超分子聚合物在智能材料和分子器件等领域的应用潜力巨大。柱芳烃的富电子空腔和易修饰刚性结构,使其成为构筑超分子聚合物的理想砌块。首先,从线性聚合物、超支化聚合物到超交联聚合物分类描述了基于柱芳烃的超分子聚合物的拓扑结构及其特性。其次,按照非共价作用的类型介绍了基于柱芳烃的超分子聚合物的构筑方法,包括氢键、金属配位键、π-π堆积、卤键和主客体作用。最后,根据外部刺激响应方式,如pH、温度、溶剂、光等,总结了基于柱芳烃的超分子聚合物的应用前景。从拓扑结构的角度,提供了一种策略来调控超分子聚合物的性质,从而实现外部响应的智能材料、缓释药物的构筑。
Supramolecular polymers are polymeric arrays of monomeric units self-assembled by non-covalent interactions. The supramolecular polymers have potential applications in the field of smart materials and molecular devices due to their self-reparability,self-adaptability,and degradability. Pillararenes serve as an ideal building block to construct the supramolecular polymers as a result of their highly symmetric and electron-rich cavity. Firstly, we described the topological structures and features of pillararene-based supramolecular polymers, containing linear, hyperbranched, and cross-linked polymers. Secondly, we introduced the synthetic strategies to prepare the pillararene-based supramolecular polymers,according to non-covalent interactions,including hydrogen bonds,metal coordination bonds,π-π stacking,halogen interactions, and host-guest interactions. Finally, we outlined the perspectives on the applications of pillararene-based supramolecular polymers based on external stimulus factors,such as pH,temperature,solvent and light. From the perspective of topological structures,we provided a strategy to realize the construction of stimulus-responsive smart materials and extended-release drugs by controlling the properties of supramolecular polymers.
