Abstract: Pyrene was used as a spectral probe in studying the interaction of some watersoluble aliphatic alcohols with β-cyclodextrin (β-CD) by fluorescence and absorption spectroseopies. Results showed that monobasic alcohol can decrease the micropolarity of β-CD cavity, but the formation constant of pyrene-β-CD inclusion complex is being larger, and polybasie alcohol had the opposite effects. The hydrogen-bonding interaction between alcohols and β-CD was proposed to explain the results.

Key words: Aliphatic alcohols, β-Cyelodextrin, Fluorescence and Absorption Spectroscopies
