Title:
IRIDIUM COMPLEX, LIGHT-EMITTING MATERIAL USING COMPOUND, AND ORGANIC LIGHT-EMITTING ELEMENT
Document Type and Number:
WIPO Patent Application WO/2017/086225
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a novel iridium complex which can be applied to an organic electroluminescent element, an organic electrochemical luminescent element, or the like, and which exhibits light emission particularly in the blue region. The iridium complex pertaining to the present invention is characterized by being represented by general formula (1). (In general formula (1): N represents a nitrogen atom; Ir represents iridium; X represents C(R6) or a nitrogen atom; R1 through R3 each independently represent a hydrogen atom, an alkyl group, an aryl group, a heterocyclic group, an alkoxy group, an amino group, an aryloxy group, or a halogen atom; and R4 through R6 each independently represent a hydrogen atom, an alkyl group, an alkoxy group, or an aryloxy group. However, at least one of R4 and R5 is an alkyl group or an alkoxy group. R1 and R2, and R2 and R3 may be bonded to form a ring structure. In general formula (1), m = 1 to 3, n = 0 to 2, and m + m = 3, and L represents a monoanionic bidentate ligand.)
