Title:
FLUORINE-SUBSTITUTED IRIDIUM COMPLEX, AND LIGHT-EMITTING MATERIAL AND ORGANIC LIGHT-EMITTING ELEMENT EACH USING SAID COMPOUND
Document Type and Number:
WIPO Patent Application WO/2017/115743
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a novel blue light-emitting iridium complex which can be used in an organic electroluminescent element, an organic electrochemical light-emitting element and others and particularly has superior sublimability compared with the conventional iridium complexes. 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; F represents a fluorine atom; Ir represents an iridium atom; R1 represents an alkyl group; m represents 2 or 3, and n represents 0 or 1, provided that m + n = 3; and L represents a monoanionic bidentate ligand.)
