摘要
Two new kinds of supramolecular inclusion compound of β cyclodextrin(host)and chloro cyclopentadi enyl tricarbonyl molybdenum(tungsten)(guest) have been prepared and characterized by using the chemical elemental analyses, infrared spectroscopy, nuclear magnetic resonance,powder X ray diffractometry and thin layer chromatography(TLC). The results show that β CD formed one to one compounds with guest and the cyclopentadienyl group of guest may be included into the hydrophobic cavity of β CD. Differential thermal analyses reveal that after formation of the supramolecular inclusion compounds, thermal stability of the host and guest molecules increased.
