Title:
BENZANTHRACENE DERIVATIVE AND ORGANIC ELECTROLUMINESCENT DEVICE USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2007/114358
Kind Code:
A1
Abstract:
Disclosed is a novel benzanthracene derivative having a hydrogen atom at the 12-position. Also disclosed is an organic electroluminescent device, wherein an organic thin film composed of one or more layers including at least a light-emitting layer is interposed between a cathode and an anode, and at least one layer of the organic thin film contains the benzanthracene derivative by itself or as a component of a mixture. The organic electroluminescent device has high luminous efficiency, long life and good chromaticity. Further disclosed is a luminescent material used for such an organic electroluminescent device.
