β-环糊精与N,N′-二(4-吡啶基甲基)-1,6-己二胺自组装包结行为的研究
Investigation of the Self-assembled Inclusion Behaviour of β-Cyclodextrin and N,N-Bis(4-pyridylmethyl)-1,6-hexanediamine
【摘要】 以4-吡啶甲醛和1,6-己二胺为原料,合成了含吡啶基的还原双席夫碱客体N,N′-二(4-吡啶基甲基)-1.6-己二胺(C6N4),通过核磁共振技术研究了β-环糊精与C6N4的自组装包结作用,测定了包结比和稳定常数．结果表明,β-环糊精与客体C6N4在水溶液中形成1∶1的包结配合物,其稳定常数的平均值为1．7×102dm3·mol-1．
【Abstract】 A reduced bis-Schiff base guest containing pyridyl, N,N′-bis(4-pyridylmethyl)-1,6-hexanediamine (C6N4), has been synthesized from 4-pyridinecarboxaldehyde and 1,6-hexanediamine. The self-assembled inclusion behaviour ofβ-cyclodextrin and linear guest C6N4 has been investigated by 1H NMR. Our experimental results revealed that a 1:1 inclusion complex ofβ-cyclodextrin and C6N4 could be formed in aqueous solution and the average value of stability constant of inclusion complex was determined to be 1.7×102 dm3·mol-1.
