(JA) 電荷輸送材料、有機発光素子および化合物
Abstract:
(EN) Using a charge transport material that comprises a compound represented by general formula (1) makes it possible to implement an organic light-emitting element having high thermal stability and low drive voltage. In general formula (1), Cz represents a 9-carbazolyl group; R represents an alkyl group, an aryl group, or a heteroaryl group; Ar represents an aromatic ring, or a connecting ring structure comprising two aromatic rings connected to each other; m represents an integer of 4 or greater; and n represents an integer of 0 or greater. General formula (1): (Cz)m–Ar–(R)n
(FR) L'invention concerne une utilisation d'un matériau de transport de charge qui comprend un composé représenté par la formule générale (1) permet de mettre en œuvre un élément électroluminescent organique ayant une stabilité thermique élevée et une faible tension d'attaque. Dans la formule générale (1), Cz représente un groupe 9-carbazolyle ; R représente un groupe alkyle, un groupe aryle ou un groupe hétéroaryle ; Ar représente un cycle aromatique, ou une structure cyclique de liaison comprenant deux cycles aromatiques reliés l'un à l'autre ; m représente un nombre entier supérieur ou égal à 4 ; et n représente un nombre entier supérieur ou égal à 0. Formule générale (1) : (Cz)m–Ar–(R)n
(JA) 下記一般式(1)で表される化合物からなる電荷輸送材料を用いることにより、熱安定性が高く、駆動電圧が低い有機発光素子を実現することができる。一般式(1)において、Czは9-カルバゾリル基、Rはアルキル基、アリール基またはヘテロアリール基、Arは芳香環、または互いに連結した2つの芳香環からなる連結環構造、mは4以上の整数、nは0以上の整数を表す。一般式(1)(Cz)-Ar-(R)
