Abstract

original image

Auf das Wesentliche reduziert: Niedermolekulare zwitterionische Materialien erweisen sich als effizientere Ladungsträgerinjektionsmaterialien als ein zuvor beschriebenes Polymer (siehe Strukturen). Die überlegenen Eigenschaften von 1 zeigen, dass man sich bei der Suche nach Materialien für die organische Elektronik nicht auf π-delokalisierte Systeme beschränken sollte und dass feste ionische Flüssigkeiten vielversprechende Kandidaten für Ladungsinjektionsmaterialien sind.
