MATERIAL FOR ORGANIC ELECTROLUMINESCENT DEVICE AND ORGANIC ELECTROLUMINESCENT DEVICE USING THE SAME

摘要

The present invention provides a novel and improved material for an organic electroluminescence device capable of enhancing the driving voltage, light emitting efficiently, and light emission life of the organic electroluminescence device; and an organic electroluminescence device including the same. The material for the organic electroluminescence device can be represented as the chemical formula 1. In the chemical formula 1, Ar_1-Ar_4 are independently substituted or unsubstituted aryl groups or substituted or unsubstituted heteroaryl groups. At least one of the Ar_1-Ar_4 is a substituted or unsubstituted aryl or heteroaryl group having ten or more carbon atoms.
