Abstract: The inclusion compound of β-cyclodcxtrin and 4,4'-bipyridyl has been prepared and characterized by using the differential thermal analyses, infrared spectroscopy, powder X-ray diffractometry and thin-layer chromatography. Chemical elemental analyses agree with calculated values. The experimental results show that β-CD formed 2: 1 host-guest compound with 4,4'-bipy molecule which was included in the hyodrophobic cavity.Although the molar ratios between host and guest in inclusion reaction were changed,the products were identical. Because of formation of the inclusion compound, thermal stability of the host and guest molecules was increased.
Keywords: synthesis  inclusion compound  β-cyclodextrin
