A new method in which supramolecular polymerization is promoted and controlled through self-sorting is reported. The bifunctional monomer containing p-phenylene and naphthalene moieties was prepared. Supramolecular polymerization is promoted by selective recognition between the p-phenylene group and cucurbit[7]uril (CB[7]), and 2:1 complexation of the naphthalene groups with cucurbit[8]uril (CB[8]). The process can be controlled by tuning the CB[7] content. This development will enrich the field of supramolecular polymers with important advances towards the realization of molecular-weight and structural control.
本文报道了一种通过自组装促进和控制超分子聚合的新方法。合成了一种含有对苯二酚和萘基部分的双功能单体。超分子聚合是通过对苯二酚基团与葫芦[7]脲(CB[7])之间的选择性识别以及萘基与葫芦[8]脲(CB[8])之间的 2:1 络合来促进的。通过调节 CB[7]的含量可以控制该过程。这一发展将丰富超分子聚合物领域,为实现分子量和结构控制提供重要进展。
