摘要
合成了1,4-二甲氧基柱E53芳烃(DMPE5]),采用核磁滴定方法研究了主体分子DMP[5]与客体分子1,6-己二胺的包结作用。通过摩尔比方法确定了主客体分子间的包结比为1:1,并利用DynaFit计算了包结常数Ka=49L/mol。本实验可作为有机化学实验在本科生化学及相关专业开设,有利于学生了解超分子化学前沿知识,激发学习兴趣,培养综合实验能力和科研方法。
1,4-Dimethoxypillar[5]arene (DMP[5]) was synthesized and the inclusion inter- actions with 1,6-diaminohexane were studied by NMR titration. The results showed that DMP [5]and 1,6-diaminohexane form a 1:1 complex with an association constant of 49 L/mol, which was calculated by DynaFit. As an organic chemistry experiment for undergraduate students, it may help students learn the leading edge of supramolecular chemistry, stimulate interests and im- prove the comprehensive ability.
