6-全脱氧-6-全氯代-β-环糊精的合成及自组装行为
Self-assembly Behavior and Synthesis of Per(6-chlorin-6-deoxy)-β-cyclodextrin
摘要
Abstract
In order to obtain the molecule with a needed structure,the modifiedβ-cyclodextrin,per(6-chlorin-6-deoxy)-β-cyclodextrin,was synthesized through the reaction of β-cyclodextrin,benzenesulfonyl chloride and imidazole in N,N-dimethylformamide(DMF).Its molecular structure was measured by X-ray crystallography,1H NMR spectroscopy,and thermogravimetric analysis(TGA).The crystal structure shows that the molecules of the compound are aligned on the a-axis to form a linear superstructure through head-to-head interactions at the primary side and tail-to-tail interactions at the secon-dary side.At the primary side,the chlorine atoms,through Cl—Cl interaction and that of hydrogen bonds,form hydropho-bic layers ,and at the secondary ,the hydroxyl groups interact through hydrogen bonds to form hydrophilic lay-ers.Thermogravimetric analysis shows that the different thermodynamic character results from the weakening of the interac-tion between the adjacentβ-cyclodextrins.关键词
