The self-assembly of 3,6-disubstituted amine-linked phenanthrene trimers with a positively charged backbone leads to the formation of vesicles in aqueous medium. Previously, it was shown that 1,6-disubstituted phosphodiester-linked pyrene trimers - possessing a negatively charged backbone - assemble into sheets. Due to electrostatic interactions of the cationic and anionic species, alternated layering of the self-assembled structures is possible. The supramolecular polymers are usually preformed in their specific environment, in order to avoid problems because of different ambient conditions. Therefore, the layering on a mica substrate is done in a stepwise procedure. The structures formed by layer-by-layer self-assembly are analyzed by microscopy.
