A Polycationic Metallodendrimer with 24 [Fe(η5 -C5 Me5 )(η6 -N-Alkylaniline)]+ Termini That Recognizes Chloride and Bromide Anions.

Pronounced dendritic effects are shown by the title compound 1 in the recognition of Cl- and Br- -this is shown by the comparison with a mononuclear compound with one dendrimer arm and a trinuclear compound with a tripodal dendrimer branch. Thus, 1 differs distinctly from 24-ferrocene dendrimers of comparable topology.
