Abstract：Inclusion complex of benzoylferrocene-thiosemicarbazone(TBF) with β-cyclodextrin(β-CD) was prepared by using kneading method. Continuous variation plot proved that 2∶3(TBF∶β-CD) inclusion complex has been formed. The characterizations of the inclusion complex were studied by UV, FTIR and X-ray diffractometry. By using the data of UV spectroscopy, the binding constant of the inclusion compound was estimated to be 5.04×1013(L4·(mol)-4), and its change in absorption with time was studied. The stability of inclusion is obviously greater than the guest molecule. Furthermore, the influences of different solvents and pH on the UV spectra of TBF and β-CD-TBF were discussed respectively. The results show that different micro-environments have apparently different effects on electric spectra of guest and inclusion complexes.
