Multifunctional supramolecular vesicles based on the complex of ferrocenecarboxylic acid capped pillar[5]arene and a galactose derivative for targeted drug delivery.

Supramolecular vesicles based on the host-guest complexation of ferrocenecarboxylic acid capped pillar[5]arene and a galactose derivative have been constructed, which showed dual-responsiveness and cancer cells targetability resulting from its ferrocenecarboxylic acid units and galactose units, respectively. This work provides a good example for the construction of multifunctional nanocarriers for targeted drug delivery.
