Abstract
(EN) An organic light-emitting device, comprising a first electrode (10), a second electrode (12), and a light-emitting layer (40) disposed between the first electrode (10) and the second electrode (12). An electron blocking layer (30) and a hole transport layer (20) are disposed between the light-emitting layer (40) and the first electrode (10). The electron blocking layer (30) is located between the hole transport layer (20) and the light-emitting layer (40). The material of the electron blocking layer (30) comprises a compound having the structure of formula (I).
(FR) L'invention concerne un dispositif électroluminescent organique, comprenant une première électrode (10), une seconde électrode (12), et une couche électroluminescente (40) disposée entre la première électrode (10) et la seconde électrode (12). Une couche de blocage d'électrons (30) et une couche de transport de trous (20) sont disposées entre la couche électroluminescente (40) et la première électrode (10). La couche de blocage d'électrons (30) est située entre la couche de transport de trous (20) et la couche électroluminescente (40). Le matériau de la couche de blocage d'électrons (30) comprend un composé ayant la structure de formule (I).
(ZH) 一种有机电致发光器件，包括：第一电极（10）、第二电极（12）以及设置在第一电极（10）和第二电极（12）之间的发光层（40）。发光层（40）和第一电极（10）之间设置有电子阻挡层（30）和空穴传输层（20）。电子阻挡层（30）位于空穴传输层（20）和发光层（40）之间。电子阻挡层（30）的材料包括具有结构式（I）的化合物。
