Indolocarbazole derivative with aromatic phosphne oxide group for organic electroluminescent device and organic electroluminescent device containing same
摘要：
Disclosed is an organic electroluminescent device (organic EL device) that is improved in the luminous efficiency, fully secured of the driving stability, and of a simple structure and disclosed also is a compound useful therefor. The organic EL device comprises a light-emitting layer disposed between an anode and a cathode piled one upon another on a substrate and the said light-emitting layer comprises a phosphorescent dopant and an indolocarbazole derivative as a host material. The indolocarbazole derivative is represented by the following formula (3) wherein Ar is an aromatic group and L is a direct bond or an aromatic group.
