摘　　要：介绍一个研究探索型大学化学综合性实验——基于葫芦[8]脲的超分子水凝胶的制备与性能研究。制备带有双键的溴化1-苄基-3-乙烯基咪唑客体(G),通过自由基聚合,将水溶性单体和客体分子G共聚得到高分子水溶液。以葫芦[8]脲为大环主体,基于主客体识别的交联作用制备了超分子水凝胶。研究发现该水凝胶具有良好的自修复性能。通过该实验,可以让学生学习葫芦脲的分离提纯及高分子的制备方法,加深对超分子聚合物的理解,掌握利用核磁等手段对材料结构及性能进行表征的技能。A chemical comprehensive experiment was recommended for the synthesis and characterization of supramolecular hydrogel.Supramolecular hydrogel was synthesized by dynamic host-guest interactions between guest units and the host molecule cucurbit[8]uril(CB[8]).It was found out that the hydrogel was self-healing.Through this experiment,students can learn how to prepare polymers,deepen their understanding of supramolecular polymers,and master the skills of characterizing the structure and properties of materials by means of NMR.
