Kern-Schale-Komposite wurden durch Einbetten eines hydrophilen Polyoxometallats (POM) in Poly(styrol-b-4-vinyl-N-methylpyridiniumiodid)-Matrices in saurer wässriger Lösung erhalten (siehe Schema). Beim Dispergieren in Toluol entstehen selbstorganisierte Micell- und Vesikelstrukturen (siehe TEM-Bilder), deren Morphologie über den POM-Anteil gesteuert werden kann.
