Abstract
(EN) An organic electroluminescent element which comprises a positive electrode and a negative electrode on a substrate, while having an organic layer between the positive electrode and the negative electrode, wherein the organic layer comprises a layer that contains an aromatic compound represented by formula (1). (In the formula, each of Ar1 to Ar5 represents a hydrogen atom or an aromatic hydrocarbon group having 6 to 60 carbon atoms; at least one of Ar1, Ar2 and Ar5 is represented by formula (2) or formula (3); each of L1 to L5 represents an aromatic hydrocarbon group having 6 to 60 carbon atoms; and R represents a specific substituent.)
(FR) L'invention concerne un élément électroluminescent organique qui comprend une électrode positive et une électrode négative sur un substrat, tout en ayant une couche organique entre l'électrode positive et l'électrode négative, la couche organique comprenant une couche qui contient un composé aromatique représenté par la formule (Dans la formule, chacun de Ar1 à Ar5 représente un atome d'hydrogène ou un groupe hydrocarboné aromatique ayant de 6 à 60 atomes de carbone ; au moins l'un de Ar1, Ar2 et Ar5 est représenté par la formule (2) ou la formule (3) ; chacun de L1 à L5 représente un groupe hydrocarboné aromatique ayant de 6 à 60 atomes de carbone ; et R représente un substituant spécifique
(JA) 基板上に、陽極及び陰極を有し、前記陽極と前記陰極の間に有機層を有する有機電界発光素子であって、前記有機層が、下記式(1)で表される芳香族化合物を含む層を有する有機電界発光素子。(Ar~Arは、水素原子又は炭素数6以上、60以下の芳香族炭化水素基。Ar、Ar及びArの少なくとも1つは下記式(2)又は式(3)で表される。L~Lは炭素数6以上、60以下の芳香族炭化水素基。Rは特定の置換基。)
