(JA) 有機電界発光素子用化合物及び有機電界発光素子
Abstract:
(EN) Disclosed is a compound for organic electroluminescent device (organic EL device) having a simple structure, which enables to improve the luminous efficiency of the device, while securing sufficient driving stability thereof. Also disclosed is an organic EL device using such a compound for organic electroluminescent device. Specifically disclosed is a compound for organic EL device having two indolocarbazole skeletons each bonded with an aromatic group or two similar skeletons. Also specifically disclosed is an organic electroluminescent device comprising a light-emitting layer between an anode and a cathode arranged on a substrate, wherein the light-emitting layer contains a phosphorescent dopant and the compound for organic EL device as a host material.
(FR) La présente invention concerne un composé pour un dispositif électroluminescent organique (dispositif EL organique) ayant une structure simple, qui permet d'améliorer l'efficacité lumineuse du dispositif, tout en assurant une stabilité d'excitation suffisante de celui-ci. La présente invention concerne également un dispositif EL organique utilisant un tel composé pour un dispositif électroluminescent organique. La présente invention concerne spécifiquement un composé pour un dispositif EL organique ayant deux squelettes indolocarbazole chacun lié avec un groupe aromatique ou deux squelettes similaires. La présente invention concerne aussi spécifiquement un dispositif électroluminescent organique qui comprend une couche émettant de la lumière entre une anode et une cathode arrangées sur un substrat, la couche émettant de la lumière contenant un dopant phosphorescent et le composé organique du dispositif EL organique en tant qu'un matériau hôte.
(JA)   素子の発光効率を改善し、駆動安定性を充分に確保し、かつ簡略な構成をもつ有機電界発光素子(有機EL素子)用化合物及びこれを使用した有機EL素子を提供する。  この有機EL素子用化合物は、芳香族基に結合するインドロカルバゾール骨格又はそれに類似する骨格を2つ有する化合物である。この有機EL素子は、基板上に積層された陽極と陰極の間に、発光層を有する有機電界発光素子であって、該発光層が、燐光発光性ドーパントと上記EL素子用化合物をホスト材料として含有する。
