合成了一种以[c2]菊链二聚体和大环主体二聚体为重复单元的新型超分子交替共聚物。这种新的组装策略的关键因素是基于[c2]菊花链伪轮烷，其在两端具有额外的未结合识别位点，这是从精心设计的异三位（AB 2型）共柱[5]芳烃成功实现的。利用双螺纹二聚体与柱[5]芳烃二聚体之间的分子间主客体相互作用，制备了线型超分子聚合物。这些结果不仅为[c2]菊链型超分子聚合物的构建提供了一种简便的途径，而且为超分子交替共聚物的构建提供了一种新的方法。
A novel supramolecular alternating copolymer with [c2]daisy-chain dimer and macrocycle host dimer as repeating units has been fabricated. A key factor for this new assembly strategy is based on a [c2]daisy-chain pseudorotaxane bearing additional unbound recognition sites at both ends, which was successfully achieved from a careful designed heterotritopic (AB2-type) copillar[5]arene. By utilizing the intermolecular host–guest interactions between the double-threaded dimer and a pillar[5]arene dimer, a linear supramolecular polymer was prepared. These results provided not only a convenient approach for the construction of [c2]daisy chain based supramolecular polymers, but also a novel method for building supramolecular alternating copolymers.
