Abstract
Official abstract text for this publication.
An organic electroluminescence device having a long lifetime and a higher emission efficiency and a specific aromatic amine derivative which provides such an organic electroluminescence device are provided. In the specific aromatic amine derivative, a dibenzofuranyl group or a dibenzothiophenyl group is bonded via a p-phenylene and a heteroaryl group is bonded via a m-phenylene. The organic electroluminescence device includes a cathode, an anode and an organic thin film layer including one or more layers which is disposed between the cathode and the anode. The organic thin film layer includes at least one light emitting layer and at least one layer of the organic thin film layer includes the aromatic amine derivative singly or in combination.
First claim
Opening claim text (preview).
What is claimed is: 1. An aromatic amine derivative represented by formula (1): wherein: R 1 represents a substituted or unsubstituted heteroaryl group having 5 to 30 ring atoms; each R 2 independently represents a substituted or unsubstituted aryl group having 6 to 30 ring carbon atoms, a substituted or unsubstituted heteroaryl group having 5 to 30 ring atoms, a sub…
