Title:
RED-EMITTING IRIDIUM COMPLEX, AND LIGHT-EMITTING MATERIAL AND ORGANIC LIGHT-EMITTING ELEMENT EACH UTILIZING SAID COMPOUND
Document Type and Number:
WIPO Patent Application WO/2017/104839
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a novel iridium complex which can be used in an organic electroluminescent element, an organic electrochemical light-emitting element and the like, exhibits properties of emitting red light having better color purity compared with the conventional compounds, and has excellent sublimation properties. The iridium complex according to the present invention is characterized by being represented by general formula (1). (In general formula (1), N represents a nitrogen atom; Ir represents an iridium atom; R1 to R9 independently represent a hydrogen atom, an alkyl group or a halogen atom; and R10 to R17 independently represent a hydrogen atom, an alkyl group, an aryl group, an alkoxy group, a heterocyclic group, an aryloxy group, a cyano group or a halogen atom.)
