A novel water soluble ditopic guest, the quaternary ammonium salt of N , N′ ‐bis(ferrocenylmethylene)‐diami‐ nobutane ( 1 ), and a known water soluble ditopic host, benzenetetracarboxylic dianhydride bridged bis( β ‐cyclo‐dextrin)s ( 2 ), have been synthesized and characterized. 1 H NMR spectra and cyclic voltammogram (CV) studies revealed the host‐guest interactions between them in aqueous solution. The supramolecular interaction also exists in solid state as confirmed by the studies of the solid samples, which were obtained by frozen‐drying the solution samples, using FTIR spectroscopy and differential scanning calorimetry (DSC) techniques. TEM measurement demonstrated that wire‐shaped supramolecular aggregates exist in the aqueous solution of the two compounds. The lengths of the aggregates could reach micrometers.
