[Study of the characterization of beta-cyclodextrin-acetylferrocene-thiosemicarbazone inclusion complex and micro-environmental effects].
Inclusion complex of acetylferrocene-thiosemicarbazone(TAF) with beta-cyclodextrin(beta-CD) has been prepared by using kneading method. Elemental analysis and the solubility determination proved that 1:1 inclusion complex has been formed. Characterization of the inclusion complex was studied by UV, FTIR, and X-ray diffractometry. The association constant was calculated to be 227 L x mol(-1) from the straight portion of the phase-solubility diagram. Furthermore, the influence of different solvents and pH on UV spectrum of acetylferrocene-thiosemicarbazone and beta-CD -TAF was discussed respectively. The results show that different micro-environment has apparently different effects on electric spectra of guest and inclusion complexes.
