Abstract
Excellent organic electroluminescent materials are needed to realize EL devices with high performance. We have succeeded in realizing bright and efficient devices with long lifetime in blue color region by the use of a new host material. The lifetime was estimated to be 21000 hr (@1000 cd/m 2 ) for the light blue devices. Furthermore, we achieved the long lifetime of 40000 hr (@1000 cd/m 2 ) in green region.Keywords
