Comparative Study on the Inclusion Interaction between meso-Tetrakis (4-N-ethylpyridiniurmyl) porphyrin and β-Cyclodextrin Derivatives
摘要:
The interaction of β-cyclodextrin (β-CD) and the modified cyclodextrins, hydroxy propyl-(-cyclodextrin (HP-β-CD), sulfobutylether-β-cyclodextrin (SBE-β-CD) and synthesized meso-tetrakis(4-N-ethylpyridiniurmyl)porphyrin (TEPyP) in aqueous solution has been studied by spectroscopic methods systematically.A significant change in fluorescence and absorption properties has been observed in the presence of β-CD, HP-β-CD and SBE-β-CD.The stoichiometry and formation constants have been determined by the steady-state fluorescence technique.The results showed that the β-CD derivatives were prior to the native β-CD and the hydrogen bonding and static electric forces played important roles in the formation of the inclusion complexes.The conformation was further confirmed by NMR spectroscopy.
