Crosslinked pi-conjugated heteroacene compound for organic electroluminescence device and organic electroluminescence device using the same |
摘要 |
Provided are an organic electroluminescence device, which: shows high luminous efficiency; is free of any pixel defect; and has a long lifetime, and a material for an organic electroluminescence device for realizing the device. The material for an organic electroluminescence device is a compound of a specific structure having aπ-conjugated heteroacene skeleton crosslinked with a carbon atom, nitrogen atom, or oxygen atom. The organic electroluminescence device has one or more organic thin film layers including a light emitting layer between a cathode and an anode, and at least one layer of the organic thin film layers contains the material for an organic electroluminescence device.
