ABSTRACT The structure of the inclusion complex of diferrocenylenone and beta-cyclodextrin prepared by a novel method of solid-grinding was studied by UV, FTIR and powder X-ray diffractometry. Continuous variation plot proved that 2 : 3 (DFE : beta-CD) inclusion complex has been formed. The binding constant of the inclusion compound was found to be 1.48 x 10(15) (L4 x mol(-4)) with the data of UV spectroscopy. Furthermore, the influence of different solvents and pH on the UV spectrum of DFE and beta-CD-DFE was discussed respectively. The results show that different micro-environment has apparently different effects on the electric spectra of guest and inclusion complex.
