Abstract
Organic-inorganic HLED materials based on silsesquioxane architectures are disclosed. These silsesquioxane compounds incorporate at least one, and preferably multiple, functional moiety substituents selected from hole transport, electron transport, and emissive material moieties and combinations thereof. The hybrid materials have OLED properties, e.g. luminescence efficiency, brilliance, turn-on voltage, longevity, etc. HLED devices fabricated with the polyhedral silsesquioxane HLED materials are disclosed. The organic-inorganic HLED devices can include multiple layers of organic-inorganic luminescent material having different functional moiety substituents to balance charge transport and emissive properties. HLED devices can be fabricated with a single layer of the organic-inorganic hybrid luminescent material that contains hole transport, electron transport, and emissive material substituent moieties on a polyhedral silsesquioxane structure.
