Abstract

Drei auf einen Streich: Die Wellenlängenabhängigkeit der nichtlinearen Absorption und Brechung eines Arylethinylruthenium-Dendrimers der ersten Generation mit Nitrophenylethinyl-Endgruppen (siehe Bild; dppe=1,2-Bis(diphenylphosphanyl)ethan) wurde für 625–1500 nm mithilfe von fs-Pulsen untersucht. Die Verbindung ist im Bereich 600–800 nm ein starker Zweiphotonenabsorber und im Bereich 1100–1200 nm ein außergewöhnlicher Dreiphotonenabsorber.
