Abstract
(EN)
An organic electroluminescent element which comprises a cathode, an anode, and organic layers disposed between the cathode and the anode, wherein the organic layers comprise a luminescent layer and an electron-transporting layer, the electron-transporting layer having been disposed between the cathode and the luminescent layer, the luminescent layer comprising a specific first compound, which is represented by any of formulae (21), (41), and (51), and the electron-transporting layer comprising a second compound, which is represented by formula (B1).
(FR)
L'invention concerne un élément électroluminescent organique qui comprend une cathode, une anode et des couches organiques disposées entre la cathode et l'anode, les couches organiques comprenant une couche luminescente et une couche de transport d'électrons, la couche de transport d'électrons ayant été disposée entre la cathode et la couche luminescente, la couche luminescente comprenant un premier composé spécifique, qui est représenté par l'une des formules (21), (41), et (51), et la couche de transport d'électrons comprenant un second composé, qui est représenté par la formule (B1).
(JA)
陰極と、陽極と、前記陰極と前記陽極との間に配置された有機層と、を含む有機エレクトロルミネッセンス素子であって、前記有機層が発光層と電子輸送層を含み、前記電子輸送層は前記陰極と前記発光層との間に配置され、前記発光層が、特定の式(21)、(41)及び(51)のいずれかで表される第1化合物を含み、前記電子輸送層が、下記式(B1)で表される第2化合物を含む、有機エレクトロルミネッセンス素子。
