Title:
BLUE PHOSPHORESCENT COMPOUND HAVING ORTHOGONAL STRUCTURED ARYL-FUNCTIONAL GROUPS LINKED THERETO AND ORGANIC LIGHT EMITTING DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2020/091344
Kind Code:
A1
Abstract:
The present invention relates to a metal complex compound with an iridium hexa-coordinated structure, based on orthogonal structured aryl-phenyl(pyridine, pyrimidine)-imidazole and aryl-phenyl(pyridine, pyrimidine)-pyridine ligands, and to a blue phosphorescent organic light emitting device using same. An organic light emitting device comprising the metal complex compound according to the present invention as a dopant compound for a light emitting layer prevents the deterioration of dopant efficiency and has durability against the non-emissive cleavage by excitons, thereby showing excellent characteristics of luminous efficiency, device stability, and lifespan and realizing deep blue color through improved color coordinates, and thus can be advantageously utilized in various display devices.
