Title (EN) ORGANIC ELECTROLUMINESCENT DEVICE
(FR) DISPOSITIF ELECTROLUMINESCENT ORGANIQUE
(JA) 有機電界発光素子
Abstract:
(EN) An organic electroluminescent device (organic EL device) of simple structure which utilizes phosphorescent emission is disclosed wherein the luminous efficiency is improved and driving stability is sufficiently secured. An organic EL device comprises an anode, a hole-transporting layer, an organic layer including a light-emitting layer and an electron-transporting layer, and a cathode which are formed in layers on a substrate. The hole-transporting layer is arranged between the light-emitting layer and the anode, while the electron-transporting layer is arranged between the light-emitting layer and the cathode. The light-emitting layer contains a pyridyl phenoxy zinc complex compound represented by the general formula (I) below as a host material and an organic metal complex containing at least one metal selected from Ru, Rh, Pd, Ag, Re, Os, Ir, Pt and Au as a guest material. (I) (In the formula, R1-R8 represent an H, alkyl group, alkenyl group, cyano group, amino group, amide group, alkoxycarbonyl group, carboxyl group, alkoxy group, aryl group or the like.)
(FR) Cette invention se rapporte à un dispositif électroluminescent organique (dispositif EL organique) de structure simple, qui utilise l'émission phosphorescente et dont le rendement lumineux est améliorée et la stabilité d'excitation est suffisamment assurée. Un tel dispositif EL organique comprend une anode, une couche de transport de trous, en couche organique contenant une couche photoémettrice et une couche de transport d'électrons, et une cathode, qui sont formées en couches sur un substrat. La couche de transport de trous est placée entre la couche photoémettrice et l'anode, alors que la couche de transport d'électrons est placée entre la couche photoémettrice et la cathode. La couche photoémettrice contient un composé de complexe de pyridyl-phénoxy-zinc représenté par la formule générale (I) comme matériau hôte et un complexe de métaux organiques contenant au moins un métal choisi parmi Ru, Rh, Pd, Ag, Re, Os, Ir, Pt et Au comme matériaux associés. Dans la formule (I) R1-R8 représentent un hydrogène, un groupe alkyle, un groupe alcényle, un groupe cyano, un groupe amino, un groupe amide, un groupe alkoxycarbonyle, un groupe carboxyle, un groupe alkoxy, un groupe aryle ou similaire.
(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燐光発光を利用した有機電界発光素子(有機EL素子)を提供する。  基板上に、陽極、正孔輸送層、発光層及び電子輸送層を含む有機層並びに陰極が積層されてなり、発光層と陽極の間に正孔輸送層を有し、発光層と陰極の間に電子輸送層を有する有機EL素子であって、発光層が、ホスト材料として下記一般式(I)で表わされるピリジルフェノキシ亜鉛錯体化合物と、ゲスト材料としてRu、Rh、Pd、Ag、Re、Os、Ir、Pt及びAuから選ばれる少なくとも一つの金属を含む有機金属錯体とを含有する有機EL素子。 (式中、R1~R8はH、アルキル基、アルケニル基、シアノ基、アミノ基、アミド基、アルコキシカルボニル基、カルボキシル基、アルコキシ基又はアリール基等を示す)
