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.展开更多
