基于主客体相互作用的超分子水凝胶是一类有趣的软物质，由于其独特的性质等而引起了人们的广泛关注。本文制备了一种基于共价键连接到Anderson簇上的金刚烷的新型有机无机杂化物，并通过包括单晶XRD和ESI-MS在内的多种技术对其进行了表征。通过H-1 NMR和ESI-MS对其与β-CD的包合物进行了系统研究。安德森-金刚烷和 6-丙烯酰胺-β-CD 复合物以及丙烯酰胺单体的自由基共聚导致了超分子水凝胶的形成，并通过扫描电子显微镜、能量色散 X 射线、X 射线光电子能谱和流变学测量对其进行了研究。该工作通过主客体相互作用成功制备了多金属氧酸盐（POM）基水凝胶，为含POM的先进功能软材料的开发提供了新途径。
Supramolecular hydrogels based on host-guest interactions constitute a class of intriguing soft matter and have attracted great attention due to their unique properties, etc. In this paper, a new organicinorganic hybrid based on covalently tethered adamantane onto an Anderson cluster was prepared and characterized by various techniques including single-crystal XRD and ESI-MS. Its inclusion complex with beta-CD was systematically investigated by H-1 NMR and ESI-MS. Radical copolymerization of the complex of Anderson-adamantane and 6-acrylamido-beta-CD, and an acrylamide monomer led to the formation of supramolecular hydrogels, which were studied by scanning electron microscopy, energy-dispersive X-ray, X-ray photoelectron spectroscopy and rheological measurements. This work presents the successful fabrication of polyoxometalate (POM)-based hydrogels through host-guest interactions, which provides a new pathway for the development of POM-containing advanced functional soft materials.
