Abstract:
Inclusion complexes between β-cyclodextrin (β-CD) and a series of dicarboxylic acids (DAn, n=11-15) were prepared by co-grinding and co-precipitation methods and the [3]pseudorotaxane structure of them was eluci-dated by FTIR, DTA and XRD characterizations. Inclusion complexes of β-CD and α,w-alkanedicarboxylate anions (DAn2-) were acquired by neutralizing β-CD/DAn different inclusion complexes with sodium hydrox-ide and the structure was also proved to be a pseudorotaxane structure by 1H-NMR spectra and NOESY spectrum. Both the inclusion complexes of β-CD/DAn and β-CD/DAn2- adopt the [3]pseudorotaxane structure with β-CD arranged in dimers threaded onto one aliphatic chain and the binding mode of 1:1 inclusion complex was excluded based on the consideration of chain conformations
Key words:  β-cyclodextrin, Inclusion complex, Dicarboxylic acid, α,ω-alkanedicarboxylate anion

摘要:
通过研磨法和共沉淀法成功制得β-环糊精与碳原子数11~15的脂肪族二元酸包合物,并通过傅立叶变换红外光谱(FTIR)、差热分析(DTA)以及X射线衍射(XRD)的方法确证了该包合物为[3]准轮烷结构.上述包合物通过与NaOH作用得到了β-环糊精与脂肪族二元酸双负离子的包合物并通过核磁共振氢谱(1H-NMR)及二维NOSEY谱确认了该包合物同样具有[3]准轮烷结构.
