In this work, two cross-linked supramolecular polymers are prepared by pillar[5]arene-based molecular recognition and coordination/oxidation of catechol. In addition, two supramolecular glues are obtained at high concentrations of the cross-linked supramolecular polymers. Both these supramolecular glues show thermo-responsiveness, while only supramolecular glue a exhibits pH-responsiveness due to the unique characteristic of the catechol–Fe3+ coordination complex. This work will be helpful for designing and preparing catechol-based supramolecular biomimetic materials and promoting the development of functional cross-linked supramolecular polymers.

基于柱[5]芳烃的主客体识别和邻苯二酚的配位/氧化构建的交联超分子聚合物网络

在这项工作中,通过基于柱[5]芳烃的分子识别和邻苯二酚的配位/氧化制备了两种交联的超分子聚合物。此外,在高浓度的交联超分子聚合物下获得了两种超分子胶。这两种超分子胶都表现出热响应性,而由于儿茶酚-Fe 3+配位络合物的独特特性,只有超分子胶a表现出pH响应性。该工作将有助于设计和制备基于儿茶酚的超分子仿生材料,促进功能性交联超分子聚合物的发展。
