Abstract

original image

Lochtransportierende Triphenylamin-Dendronen als Liganden in Iridium-Elektroleuchtstoffen ergeben hocheffiziente, rein rote organische Leuchtdioden (siehe Bild). Diese difunktionellen Dendrimere haben eine Signaleffizienz von 11.7 % bei ausgezeichneter Farbqualität und eröffnen einen Zugang zu metallhaltigen Leuchtstoffen mit dem optimierten Effizienz/Farbreinheits-Ausgleich, der für rein rot emittierende Bauteile erforderlich ist.
