Abstract

original image

Ein gesundes Strahlen: Eine Serie von Palladium(II)-Komplexen mit vierzähnigen O N C N-Liganden (siehe Struktur) wurde entwickelt. Die Komplexe zeigen eine intensive grüne Phosphoreszenz sowie langlebige Anregungszustände mit Emissionsquantenausbeuten bis 22 % und Lebensdauern bis 122 μs. Sie bieten vielversprechende Perspektiven für Anwendungen in der Sauerstoffsensorik, der Photokatalyse und in organischen Leuchtdioden.
