安定で効率的なエレクトロルミネセンス材料

Document Type and Number:

Japanese Patent JP5009154

Kind Code:

B2

Abstract:

A compound of Formula I and an organic light emitting device is provided. The device has an anode, a cathode, and an emissive layer disposed between the anode and the cathode. The emissive layer may include a molecule of Formula I wherein an alkyl substituent at position R'₅ results in high efficiency and operational stability in the organic light emitting device. Additionally or alternatively, the emissive layer may include a metal-ligand complex in which the ligand is an aryl or alkyl substituted phenylpyridine ligand.
