Title:
ORGANIC ELECTROLUMINESCENT ELEMENT
Document Type and Number:
WIPO Patent Application WO/2011/024977
Kind Code:
A1
Abstract:
Disclosed is a red phosphorescent material that emits light with excellent color and has easy sublimation and evaporation. Specifically disclosed is an organic metal complex that is characterized by being represented by the general formula (1). (A represents an aromatic heterocycle comprising nitrogen atoms, and B represents an aromatic ring or an aromatic heterocycle. In regards to a least one pair of A and B, A represents a quinoline ring or an isoquinoline ring, and B represents a naphthalene. A and B may each be provided with a substituent, and may also be a fused ring. R1 and R3 each independently represent an alkyl group, an aryl group, or a heteroaryl group. R2 represents a hydrogen atom, an alkyl group, an aryl group, a heteroaryl group, or a halogen atom. Additionally, at least one of R1, R2, and R3 comprises at least one or more fluorine atoms.)
