Title (EN) ORGANIC ELECTROLUMINESCENT ELEMENT, AND ELECTRONIC DEVICE
(FR) ÉLÉMENT ÉLECTROLUMINESCENT ORGANIQUE ET DISPOSITIF ÉLECTRONIQUE
(JA) 有機エレクトロルミネッセンス素子、及び電子機器
Abstract:
(EN) An organic electroluminescent element has an anode, a luminous layer, and a cathode. The luminous layer contains a first compound and a second compound. The first compound is a delayed fluorescent compound. The second compound is expressed by general equation (20) noted below. Singlet energy S1 (M1) of the first compound and singlet energy S1 (M2) of the second compound satisfy the relationship of the mathematical formula noted below (Formula 1). S1 (M1) > S1 (M2)...(Formula 1)
(FR) L'invention concerne un élément électroluminescent organique qui a une anode, une couche lumineuse et une cathode. La couche lumineuse contient un premier composé et un second composé. Le premier composé est un composé fluorescent retardé. Le second composé est exprimé par l'équation générale (20) indiquée ci-dessous. L'énergie singulet S1 (M1) du premier composé et l'énergie singulet S1 (M2) du second composé satisfont la relation de la formule mathématique indiquée ci-dessous (Formule 1). S1(M1) > S1(M2)… (Formule 1)
(JA) 陽極と、発光層と、陰極と、を有し、前記発光層は、第一の化合物、及び第二の化合物を含み、前記第一の化合物は、遅延蛍光性の化合物であり、前記第二の化合物は、下記一般式(20)で表される化合物であり、前記第一の化合物の一重項エネルギーS(M1)と、前記第二の化合物の一重項エネルギーS(M2)とが、下記数式(数1)の関係を満たす、有機エレクトロルミネッセンス素子。 S(M1)>S(M2) …(数1)
