The success of exploiting cucurbit[]uril (CB[])-based molecular recognition in self-assembled systems has sparked a tremendous interest in polymer and materials chemistry. In this study, polymerization in the presence of host-guest complexes is applied as a modular synthetic approach toward a diverse set of CB[8]-based supramolecular hydrogels with desirable properties, such as mechanical strength, toughness, energy dissipation, self-healing, and shear-thinning. A range of vinyl monomers, including acrylamide-, acrylate-, and imidazolium-based hydrophilic monomers, could be easily incorporated as the polymer backbones, leading to a library of CB[8] hydrogel networks. This versatile strategy explores new horizons for the construction of supramolecular hydrogel networks and materials with emergent properties in wearable and self-healable electronic devices, sensors, and structural biomaterials. © 2017 The Authors.

在自组装体系中利用基于葫芦脲（CB[]）的分子识别取得的成功，引发了聚合物和材料化学领域的极大兴趣。在本研究中，在主客体复合物存在下进行聚合反应被用作一种模块化合成方法，用于制备一系列具有理想性能（如机械强度、韧性、能量耗散、自愈合和剪切变稀）的基于CB[8]的超分子水凝胶。一系列乙烯基单体，包括基于丙烯酰胺、丙烯酸酯和咪唑鎓的亲水性单体，可以很容易地作为聚合物主链引入，从而形成一个CB[8]水凝胶网络库。这种通用策略为构建具有新兴特性的超分子水凝胶网络和材料开拓了新视野，这些材料可应用于可穿戴和自愈合电子设备、传感器以及结构生物材料中。© 2017作者。《聚合物科学杂志》A辑：聚合物化学，由Wiley Periodicals, Inc.出版。J.
