IRIDIUM COMPLEX COMPOUND, COMPOSITION CONTAINING SAID COMPOUND AND SOLVENT, ORGANIC ELECTROLUMINESCENT ELEMENT CONTAINING SAID COMPOUND, DISPLAY DEVICE AND ILLUMINATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/107467
Kind Code:
A1
Abstract:
This iridium complex compound is represented by formula (1). Ir is an iridium atom. L is a bidentate ligand. The ring Cy1 is an aromatic ring or a heteroaromatic ring containing carbon atoms C1 and C2. The ring Cy2 is a heteroaromatic ring containing a carbon atom C3 and a nitrogen atom N1. R1 and R2 are hydrogen atoms or substituents. a and b are the maximum integer number of substitutions possible on ring Cy1 and ring Cy2, respectively. m is 1 to 3, n is 0 to 2, and m + n = 3. At least one R1 is represented by formula (2). R5 to R11 are hydrogen atoms or substituents. Rx1 and Rx2 are alkyl groups or aralkyl groups.
