Abstract
Novel linear supramolecular polymers were constructed by the orthogonal self-assembly of a heteroditopic monomer and a homoditopic monomer. The polymerization is driven by a combination of quadruple hydrogen bonding and benzo-21-crown-7 based host-guest complexation. The disassembly-assembly of these novel polymers could be reversibly switched by addition/removal of K(+).
摘要
新型线性超分子聚合物通过杂双功能单体和同双功能单体的正交自组装构建而成。聚合反应由四重氢键和基于苯并-21-冠-7 的主体-客体络合作用共同驱动。通过添加/去除 K(+)，这些新型聚合物的组装-解组装可以可逆切换。
