摘要
苷脲和多聚甲醛在盐酸存在下反应，合成了多种聚合度的混合瓜环{Q[n]，n=5-8}；利用其在盐酸中的溶解性差异，通过连续分离得到了单聚合度的Q[5]-Q[8]，其结构经^1H NMR表征。
Cucurbit [ n ] uril { Q [ n ], n = 5 - 8 t with multi-degree of polymerization was synthesized from glycoluril and paraformalhehyde in the presence of HCl. Q[ n] was separated continuously to obtain Q[5] - Q[ 8] with single-degree by solubility difference of Q[ n] in HCl solution. The structures were characterized by ^1H NMR.
