Document Type and Number:
WIPO Patent Application WO/2019/056515
Kind Code:
A1
Abstract:
A multi-substituted quinolone-coordinated iridium-hybridized compound and a preparation method therefor, as well as an application of the compound in electroluminescent materials. Ligand modification of the compound comprises second position-substituted 3,5 di-substituted (RdRd), fourth position-substituted (Re) and 3, 4, 5 trisubstituted (RdReRd) phenyl; the specific synthesis route of the multi-substituted quinoline-coordinated iridium-hybridized compound is as follows: by means of an amine transesterification reaction, a Skraup ring condensation reaction under the catalysis of acid and a hydroxyhalogenation reaction, multi-substituted quinoline is formed, and then a ligand is obtained by means of a Suzuki coupling reaction.
