Final Report Abstract
Zusammenfassend haben wir erfolgreich eine effiziente Methode für die Herstellung von löslichen und gut definierten Monolithiumsalz Alkylzink-Alkoxo Cubane mit einem [LiZn3O4] Kern und verschiedenen Alkoxy (iPr und tBu) und Alkylgruppen (R an Zink = Me, Et) entwickelt. Unsere Ergebnisse beweisen, dass diese Cubane geeignete metallorganische SSPs zur Herstellung von Lithium-enthaltenden ZnO-Nanokristallen sind. Die faszinierend einfache und effiziente Synthese ermöglicht den Zugang zu reinen Li-haltigen ZnO Materialien, die in vielen Bereichen wie Optoelektronik, Katalyse und in der Photovoltaik Anwendung finden.
