Binding interactions between the host cucurbit[7]uril and dendrimer guests containing a single ferrocenyl residue.

The stability of the inclusion complexes formed between the host cucurbit[7]uril and dendrimers containing a single ferrocene residue is strongly affected by the solution pH and the growth of the dendrimer, reaching its highest values on the second and third generation dendrimers, whereas no complex is formed with the first generation compound.
