(EN) COMPOSITION, PHOSPHORESCENT COMPOUND, AND LIGHT-EMITTING ELEMENT
(FR) COMPOSITION, COMPOSÉ PHOSPHORESCENT, ET ÉLÉMENT ÉLECTROLUMINESCENT
Abstract:
(EN) Disclosed is a composition in which a phosphorescent compound represented by formula (1) and a host material are blended with each other, wherein the amount of chlorine atoms contained as impurities in the phosphorescent compound is 3.5 ppm by mass or less with respect to the total amount of solid contents blended in the composition: wherein, M 1 represents an iridium atom or the like; n 1 represents an integer of 1 or more, n 2 represents an integer of 0 or more, and n 1 + n 2 is 2 or 3; E 1 and E 2 represent a carbon atom or a nitrogen atom; R 1 ring represents a 5-membered aromatic heterocyclic ring and R 2 ring represents an aromatic hydrocarbon ring or the like; A 1 -G 1 -A 2 represents an anionic bidentate ligand; A 1 and A 2 represent a nitrogen atom or the like; and G 1 represents a single bond or the like.
(FR) L'invention concerne une composition dans laquelle un matériau hôte est mélangé avec un composé phosphorescent représenté par la formule (1) et dans laquelle la quantité d'atomes de chlore contenus à titre d'impureté dans le composé phosphorescent est inférieure ou égale à 3,5 ppm en masse par rapport à la teneur totale en solides mélangés dans la composition. [Dans la formule, M1 représente un atome d'iridium ou analogue ; n1 représente un nombre entier supérieur ou égal à 1, n2 représente un nombre entier supérieur ou égal à 0, et la valeur de n1 + n2 est égale à 2 ou 3 ; E1 et E2 représentent chacun un atome de carbone ou un atome d'azote ; le noyau R1 représente un noyau hétérocyclique aromatique à 5 chaînons, et le noyau R2 représente un noyau hydrocarboné aromatique ou similaire ; A1-G1-A2 représente un ligand bidentate anionique ; A1 et A2 représentent chacun un atome d'azote ou similaire ; et G1 représente une liaison simple ou similaire.]
