The missing link: Supramolecular transformation from a vesicle to a fibrous nanostructure has been achieved by photolytic cleavage and supramolecular reorganization of a dendritic building block containing a 2-nitrobenzyl group (see picture). Furthermore, supramolecular aggregates of an amide dendron with a photoisomerizable azobenzene unit exhibit controlled release of encapsulated molecules upon photoirradiation in the aqueous phase.
