(FR) MATERIAUX ELECTROLUMINESCENTS STABLES ET EFFICACES
Abstract: front page image
(EN)An organic light emitting device is provided. The device has an anode, a cathode, and an emissive layer disposed between the anode and the cathode. The emissive layer may include a molecule of Formula (I) wherein an alkyl substituent at position R'5 results in high efficiency and operational stability in the organic light emitting device. Additionally or alternatively, the emissive layer may include a metal-ligand complex in which the ligand is an aryl or alkyl substituted phenylpyridine ligand.
(FR)L'invention concerne un dispositif électroluminescent organique. Le dispositif comprend une anode, une cathode et une couche émissive disposée entre l'anode et la cathode. La couche émissive peut comprendre une molécule de formule I dans laquelle un substituant alkyle à la position R'5 permet d'obtenir un rendement élevé et une stabilité fonctionnelle dans le dispositif électroluminescent organique. De plus ou de manière alternative, la couche émissive peut comprendre un complexe métal-ligand dans lequel le ligand est un ligand de phénylpyridine substitué par aryle ou alkyle.
