Abstract
(EN) Provided are: a practically useful organic EL element having high efficiency and long service life while having a low driving voltage; and a deuteride suitable for the same.　The deuteride has a hydrogen atom on an aromatic ring in Ar1 and Ar2 of a compound represented by general formula (1) and has a deuteration percentage of at least 40%. (Here, Ar1 and Ar2 each independently represent a substituted or unsubstituted aromatic hydrocarbon group having 6-30 carbon atoms, or a substituted or unsubstituted linked aromatic group in which two to five among these aromatic rings are linked, and an aromatic hydrocarbon group for linking may be the same as or different from each other.)
(FR) L'invention concerne : un élément électroluminescent organique utile sur le plan pratique ayant une efficacité élevée et une longue durée de vie tout en ayant une faible tension de commande ; et un deutérure approprié pour celui-ci.　Le deutérure a un atome d'hydrogène sur un cycle aromatique dans Ar1 et Ar2 d'un composé représenté par la formule générale (1) et a un pourcentage de deutération d'au moins 40 %. (Ici, Ar1 et Ar2 représentent chacun indépendamment un groupe hydrocarboné aromatique substitué ou non substitué ayant de 6 à 30 atomes de carbone, ou un groupe aromatique lié substitué ou non substitué dans lequel deux à cinq parmi ces cycles aromatiques sont liés, et un groupe hydrocarboné aromatique pour la liaison peut être identique ou différent l'un de l'autre.)
(JA) 低駆動電圧でありながら、高効率かつ長寿命を有した実用上有用な有機ＥＬ素子及びそれに適する重水素化物を提供する。　下記一般式（１）で表される化合物のＡｒ１及びＡｒ２における芳香族環上の水素原子の重水素化率が４０％以上である重水素化物である。　 （ここで、Ａｒ１及びＡｒ２はそれぞれ独立に、置換若しくは未置換の炭素数６～３０の芳香族炭化水素基、又はこれらの芳香族環が２～５個連結してなる置換若しくは未置換の連結芳香族基を示し、連結する場合の芳香族炭化水素基は同一であっても異なっていてもよい。）
