Material for organic electroluminescent device and organic electroluminescent device using same
Abstract:
The present invention provides an organic electroluminescent device material composed of an aromatic amine derivative having a specific structure in which amine moieties are linked to a chrysene moiety; and an organic electroluminescent device having a cathode, an anode, and one or more organic thin-film layers interposed between the cathode and the anode, the organic thin-layers including at least a light-emitting layer, wherein at least one of the organic thin-film layers contains the organic electroluminescent device material in the form of single component material or a mixture of a plurality of components. The organic electroluminescent device material and the organic electroluminescent device containing the material attains a long service life and can emit blue light of high color purity at high emission efficiency.
