ORGANIC METAL COMPLEX AND ORGANIC ELECTROLUMINESCENT DEVICE USING SAME

摘要

Disclosed is an organic electroluminescent device (organic EL device) having an improved luminous efficiency, an adequate driving stability and a simple structure. Also disclosed is an organic metal complex suitable for such an organic electroluminescent device. Specifically disclosed is an organic metal complex represented by the following general formula (I). (I) (In the formula, Ar1 represents an optionally substituted aromatic hydrocarbon group or a heteroaromatic group; Ar2 and Ar3 respectively represent an optionally substituted aromatic hydrocarbon group or a heteroaromatic group; M represents a trivalent metal; and L represents an arylate ligand containing a heterocyclic moiety having at least one nitrogen atom coordinatable with M as a ring-constituting atom.) This organic metal complex is suitable as a material which constitutes a light-emitting layer of an organic EL device together with a phosphorescent dopant. ® KIPO & WIPO 2008
