Complexation of Ferrocene Derivatives by the Cucurbit[7]uril Host: A Comparative Study of the Cucurbituril and Cyclodextrin Host Families

Original language description

The formation of inclusion complexes between cucurbit[7]uril (CB[7]) and ferrocene and its derivs. has been investigated. The x-ray crystal structure of the 1:1 inclusion complex between ferrocene and CB[7] revealed that the guest mol. resides in the host cavity with two different orientations. Inclusion of a set of five water-sol. ferrocene derivs. in CB[7] was investigated by 1H NMR spectroscopy and calorimetric and voltammetric techniques. Data indicate that all neutral and cationic guests form highly stable inclusion complexes with CB[7], with binding consts. in the 109-1010 M-1 and 1012-1013 M-1 ranges, resp. However, the anionic ferrocenecarboxylate, the only neg. charged guest among those surveyed, was not bound by CB[7] at all. These results are in sharp contrast to the known binding behavior of the same guests to b-cyclodextrin (b-CD), since all the guests form stable inclusion complexes with b-CD, with binding consts. in the range 103-104 M-1.
