Abstract:
(EN) A light emitting element having an anode, a cathode, a first luminescent layer provided between the anode and the cathode, and a second luminescent layer provided between the anode and the cathode. The first luminescent layer contains a metal complex expressed by formula (1). (In the formula, M1 represents an iridium atom, etc. n1 represents an integer of 1 or greater, n2 represents an integer of 0 or greater, and n1+n2 is 2 or 3. Ring R1A represents, inter alia, a triazole ring or the like constituted by a nitrogen atom, E1, E11A, E12A, and a carbon atom. Ring R2 represents an aromatic hydrocarbon ring, etc. E1, E2, E11A, and E12A represent nitrogen atoms, etc. R11A and R12A represent aryl groups, etc. R13A represents an aryl group, etc. A1-G1-A2 represents an anionic bidentate ligand. A1 and A2 represent nitrogen atoms, etc. G1 represents a single bond, etc.)
(FR) L'invention concerne un élément électroluminescent comprenant une anode, une cathode, une première couche luminescente disposée entre l'anode et la cathode, et une seconde couche luminescente disposée entre l'anode et la cathode. La première couche luminescente contient un complexe métallique exprimé par la formule (1). (Dans la formule, M1 représente un atome d'iridium, etc. n1 représente un nombre entier supérieur ou égal à 1, n2 représente un nombre entier supérieur ou égal à 0, et la relation n1 + n2 est égale à 2 ou 3. Le cycle R1A représente entre autres un cycle triazole ou similaire constitué d'un atome d'azote, de E1, de E11A, de E12A, et d'un atome de carbone. Le cycle R2 représente un cycle hydrocarboné aromatique, etc. E1, E2, E11A, et E12A représentent des atomes d'azote, etc. R11A et R12A représentent des groupes aryle, etc. R13A représente un groupe aryle, etc. A1-G1-A2 représente un ligand bidentate anionique. A1 et A2 représentent des atomes d'azote, etc. G1 représente une liaison simple, etc.)
(JA) 陽極と、陰極と、陽極及び陰極の間に設けられた第1の発光層と、陽極及び陰極の間に設けられた第2の発光層とを有し、第1の発光層が、式(1)で表される金属錯体を含有する、発光素子。 [式中、Mはイリジウム原子等を表す。nは1以上の整数を表し、nは0以上の整数を表し、n+nは2又は3である。環R1Aは、窒素原子、E、E11A、E12A及び炭素原子で構成されるトリアゾール環等を表す。環Rは、芳香族炭化水素環等を表す。E、E、E11A及びE12Aは、窒素原子等を表す。R11A及びR12Aは、アリール基等を表す。R13Aは、アリール基等を表す。A-G-Aは、アニオン性の2座配位子を表す。A及びAは、窒素原子等を表す。Gは、単結合等を表す。]
