| 摘要 |
The present invention relates to a novel solution processable red-emitting iridium (III) complex. In the iridium (III) complex, a quinoline-thiophene derivative is introduced as a main ligand and a picolinic acid derivative substituted with a halogen, a substituent having electron transporting properties or a substituent having hole transporting properties is introduced as an ancillary ligand at the para-position relative to the nitrogen atom of picolinic acid. The iridium (III) complex is a red phosphorescent compound that is highly electrically stable, exhibits excellent luminescent properties and high luminance, and has high color purity. In addition, the iridium (III) complex has improved solubility in organic solvents and good resistance to heat, ensuring excellent interfacial properties with electrodes. Therefore, the iridium (III) complex is useful as a light emitting material for an organic electroluminescence device. The present invention also relates to an organic electroluminescence device including the iridium (III) complex. |
