Photoinduced release of guest molecules by supramolecular transformation of self-assembled aggregates derived from dendrons

Article abstract of DOI:10.1002/anie.200705271

The missing link: Supramolecular transformation from a vesicle to a fibrous nanostructure has been achievedby photolytic cleavage andsupramolecular 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 controlledrelease of encapsulated molecules upon photoirradiation in the aqueous phase.
