Polymeric onions : A concept of vesicle fabrication based on nonstoichiometric complexation of a polybase with an amphiphilic ligand bearing a sulfonic acid group is developed (see picture). In contrast to conventional polymersomes, the polymer backbones are oriented mainly parallel to the vesicle walls. The vesicles can collapse under UV irradiation because of a UV‐triggered trans – cis isomerization of the azo‐group‐containing ligand.
