Abstract

original image

Besser undotiert: Ein Dendron mit einer hohen Carbazoldichte um einen Iridiumkern verbessert die Leistung nichtdotierter elektrophosphoreszenter Einheiten effektiver als Dendrimere höherer Generationen. Eine vielversprechende Effizienz von 45.7 cd A−1 (13.4 %) und eine hohe Luminanz zeigt 6 B-G1 (siehe Bild). Diese Werte liegen sehr nahe an denen der entsprechenden dotierten Einheit.
