Zusammenfassung:The objective of the present invention is to provide a light-emitting material, for an organic EL device, exhibiting higher light-emitting efficiency, and, in particular, to provide a blue light-emitting material. Particularly, the objective of the present invention is to provide a blue light-emitting material suitable for an organic EL device which is excellent in productivity and uses a coating method. The present invention is characterized by using a compound of general formula (1) below as a light-emitting material of an organic EL device. General formula (1) (in general formula (1), X and Y represent substituents, X and Y are not the same, X is an aryl group including a tertiary-amine structure, and Y is a phenyl group having an alkyl or aryl substituent at one ortho-position.) L'objectif de la présente invention est de fournir un matériau électroluminescent, pour un dispositif électroluminescent organique, présentant une efficacité d'émission de lumière supérieure et, en particulier, de fournir un matériau électroluminescent bleu. En particulier, l'objectif de la présente invention est de fournir un matériau électroluminescent bleu approprié pour un dispositif électroluminescent organique qui présente une excellente productivité et utilise un procédé de revêtement. La présente invention est caractérisée en ce qu'elle utilise un composé ayant la formule générale (1) ci-dessous en tant que matériau électroluminescent d'un dispositif électroluminescent organique. Formule générale (1) (dans la formule générale (1), X et Y représentent des substituants, X et Y ne sont pas identiques, X est un groupe aryle comprenant une structure amine tertiaire, et Y est un groupe phényle ayant un substituant alkyle ou aryle à une position ortho.) 본 발명은, 유기 EL 디바이스를 위한, 보다 높은 발광 효율을 나타내는 발광 재료, 특히 청색 발광 재료를 제공하는 것을 목적으로 한다. 특히, 소자의 생산성이 뛰어난, 도포법에 의한 유기 EL 디바이스에 적합한 청색 발광 재료를 제공하는 것을 목적으로 한다. 본 발명은, 하기 일반식 (1)의 화합물을, 유기 EL 디바이스의 발광 재료로서 사용하는 것을 특징으로 한다. 일반식 (1) (일반식 (1)에 있어서, X 및 Y는 치환기를 나타내고, X와 Y는 서로 동일하지는 않고, X는 제3급 아민 구조를 포함하는 아릴기이며, Y는 1개의 오르토 위치에 알킬 또는 아릴 치환기를 갖는 페닐기이다. )
