Study on molecular interaction of inclusion complex between β-cyclodextrin and nicotine
【Abstract】 The molecular interaction of inclusion complex between βcyclodextrin(βCD)and nicotine in aqueous solutions was studied by UVVis spectrophotometric and proton nuclear magnetic resonance(1HNMR)spectroscopy.It was found that the inclusion complex between βCD and nicotine can also be formed in alkaline aqueous solutions at pH=105.The result can be further proved by a competitive inclusion process using phenolphthalein as a probe.A solid with supermolecular structure of βCD/nicotine was prepared,and its powder Xray diffraction data indicated that the crystalline structure of inclusion complex is different from the original βCD crystalline structure.The result of differential scanning calorimetry(DSC)can also confirm this conclusion.
