This mini-review reports on novel complex macromolecular architectures based on star-shaped polyions. They can be prepared in aqueous media via electrostatically driven co-assembly of the polyelectrolyte stars (a) with oppositely charged linear homopolyelectrolytes or (b) with oppositely charged double hydrophilic (ionic/non-ionic) diblock copolymers. In the case (a) the complex macromolecular architectures (interpolyelectrolyte complexes) are water-soluble only if charge of a star-shaped macromolecule is partially compensated by a linear polyion. In the case (b), the interpolyelectrolyte complexes remain their solubility in aqueous media even under a full charge compensation of the polymeric components. In both cases, the complex macromolecular architectures are characterized by a distinct compartmentalized structure of a micellar (core-corona) type with an insoluble core, which is assembled from coupled monomer units of the oppositely charged polymeric components, and a hydrophilic, either ionic or non-ionic, corona.
