Paragraph 0152-0155, (2019/08/06)
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.(110) First electrode(120) Second electrode(AA) Smooth interface morphology ↑COPYRIGHT KIPO 2019

A new catalyst system capable of selective chloride functionalization in the Pd-catalyzed amination of 3,2- and 5,2- Br/Cl-pyridines is reported. A reaction optimization strategy employing ligand parametrization led to the identification of 1,1′-bis[bis(dimethylamino)phosphino]ferrocene "DMAPF", a readily available yet previously unutilized diphosphine, as a uniquely effective ligand for this transformation.
