ORGANIC COMPOUND, AND LIGHE-EMITTING DIODE AND LIGHT-EMITTING DEVICE COMPRISING SAME

摘要

The present invention relates to an organic compound having an amine core substituted with three aromatic rings, wherein a part of the three aromatic rings is substituted with a functional group capable of a solution process while the rest of the three aromatic rings is substituted with a hetero-aromatic functional group; and a light-emitting diode and a light-emitting device having the organic compound applied to a light-emitting layer. The organic compound may be used to the light-emitting layer to eliminate the HOMO energy barrier between the light-emitting layer and another light-emitting layer adjacent thereto. Also, the organic compound, when it forms a light-emitting layer in combination with light-emitting particles, may improve interfacial properties between the light-emitting layer and an adjacent layer to improve morphological properties of the light-emitting diode. The organic compound of the present invention, by allowing holes and electrons to be transported and implanted into a light emitting material layer in a balanced manner, may implement light-emitting diodes and light-emitting devices with improved luminance efficiency and capable of low-voltage driving.;COPYRIGHT KIPO 2019
