摘要/Abstract
合成了一种同时含有脲基嘧啶酮基团（UPy）和苯并21冠7基团（B21C7）的单体H以及一种同时含有两个二烷基铵盐单元的单体G.分子H和G中的功能基团均由短间隔基相连.H可以通过四重氢键形成二聚体，进而和G发生主客体组装形成线性超分子共聚物.对该超分子共聚物进行了如下表征：随浓度变化1H NMR，粘度测试以及扫描电子显微镜（SEM）等.该结果将启发在更多领域中利用正交策略构筑各种超分子聚合物智能材料.

A heteroditopic monomer (H) comprised of ureidopyrimidinone (UPy) group and benzo-21-crown-7 motif and a homoditopic monomer (G) containing two dialkylammonium salt units have been successfully prepared. The functional groups both in H and G are linked together by a short spacer. Through quadruple hydrogen bonds, H can self-assemble into dimers, which are capable of complexing with G via host-guest interaction to form linear supramolecular copolymers. The supramolecular copolymers were fully characterized by various techniques, such as concentration-dependent 1H NMR, viscosity measurements, and scanning electron microscope (SEM). The results will inspire the orthogonal construction of supramolecular polymers for smart materials in more fields.
