| 摘要 |
The present invention relates to a novel iridium (III) complex compound capable of being solution-processed and an organic electroluminescent device comprising same, and more specifically, to a novel iridium (III) complex compound into which a piconolic acid derivative is introduced and an organic electroluminescent device comprising the iridium (III) complex compound, wherein in the iridium (III) complex compound, a quinolone- and a thiophene-derivative are introduced as main ligands, and a halogen derivative or an oxadiazole derivative exhibiting electron transport characteristics is introduced as a substituent on the para position of a nitrogen atom in picolinic acid, as ancillary ligands. The iridium (III) complex compound, according to the present invention, is a red light-emitting phosphorescent compound which has excellent electric stability, high light-emitting characteristics and luminance, is capable of achieving color purity, has improved solubility with respect to an organic solvent, and has excellent interfacial characteristics with an electrode due to improved heat resistance, and thus can be useful as a color-developing material. |
