| 摘 要： | 本文研究了β-环糊精(主体)与联苯及其衍生物(客体)的包合反应。用多种谱学方法对固体包合物进行了表征, 由连续变量法确定了主-客体包合物组成均为2:1, 根据高分辨核磁共振光谱主体内腔质子(3-H)化学位移的变化求出了包合物的稳定常数, 对包合物的形成进行了初步讨论。

Study on the inclusion compounds of β-cyclodextrin with diphenyl and its derivates |
| |
| Abstract: | The inclusion compounds of β-cyclodextrin(host) with diphenyl and its derivates (p-hydroxydiphenyl; 2,2'-dihydroxydiphenyl; 4,4'-dihydroxydiphenyl) (guest) were prepared. The properties of these compounds were investigated by using the thermogravimetry-differential thermal analyses, powder X-ray diffractometry, nuclear magnetic resonance and infrared spectroscopy. The experimential results demonstrated that all the inclusion compounds were found to be 2:1 and their inclusion equilibrium contants (K) were obtained approximately by NMR method. The possible structure and the driving force for these compounds were discussed. |
