Die Erfindung betrifft eine organische Leuchtdiode (OLED) mit verbesserter Lebensdauer und verbessertem Transport negativer Ladungsträger. Die organische Leuchtdiode auf der Basis eines organischen halbleitenden Materials, in dem der Transport negativer Ladungsträger und die Stabilität bezüglich Reduktion durch Azahetarylen-Lewissäure-Komplex-Einheiten bestimmt werden. Dies führt zu einer verbesserten Lebensdauer der Emissionsschicht, was zum einen die Lebensdauer des Bauteils erhöht und ein Nachregeln der Helligkeit während des Betriebs vermeidet. Außerdem betrifft die Erfindung solche organische Leuchtdioden, in denen durch Azahetarylen-Lewissäure-Komplex-Einheiten die Lage der Emissionszone in der Emitterschicht und die Farbe der Emission gezielt beeinflusst werden können.

Die Erfindung betrifft phosphoreszierende bzw. lumineszierende konjugierte Polymere, deren Emission auf Phosphoreszenz kovalent gebundener Metallkomplexe gegebenenfalls in Kombination mit Fluoreszenz der Polymerkette basiert, ein Verfahren zu deren Herstellung sowie deren Anwendung in elektrolumineszierenden Anordnungen.
摘要:
The invention comprises a composite material comprising a host material in which are incorporated semiconductor nanocrystals. The host material is light-transmissive and/or light-emissive and is electrical charge-transporting thus permitting electrical charge transport to the core of the nanocrystals. The semiconductor nanocrystals emit and/or absorb light in the near infrared spectral range. The nanocrystals cause the composite material to emit/absorb energy in the near infrared (NIR) spectral range, and/or to have a modified dielectric constant, compared to the host material. The invention further comprises electro-optical devices composed of this composite material and a method of producing them. Specifically described are light emitting diodes that emit light in the NIR and photodetectors that absorb light in the same region.
