This invention relates to an organic compound having an amine core substituted with three aromatic rings, with some of the aromatic rings being substituted with substituents capable of liquid processing, and other aromatic rings being substituted with heteroaromatic substituents. The invention also pertains to an organic compound applied to a light-emitting layer in a light-emitting diode and a light-emitting device. By using the organic compound according to the invention in the light-emitting layer, it is possible to eliminate the HOMO energy barrier between the light-emitting layers adjacent to each other. Furthermore, when the organic compound of the invention is used in combination with light-emitting particles to form the light-emitting layer, the interfacial characteristics between the light-emitting layer and adjacent layers are improved, enhancing the morphology characteristics of the light-emitting diode. By applying the organic compound according to the invention, it is possible to achieve improved luminous efficiency and manufacture light-emitting diodes and light-emitting devices capable of low-voltage operation due to the balanced movement of holes and electrons in the light-emitting material layer.
Versatile routes for synthesis of diarylamines through acceptorless dehydrogenative aromatization catalysis over supported gold–palladium bimetallic nanoparticles
palladium nanoparticle catalyst (Pd/TiO2) gave the desired diarylamines, the catalyticactivity was inferior to that of Au–Pd/TiO2. Moreover, the activity of Au–Pd/TiO2 was superior to that of a physical mixture of Au/TiO2 and Pd/TiO2. The present Au–Pd/TiO2-catalyzed transformation of cyclohexylamines proceeds through complex pathways comprising amine dehydrogenation, imine disproportionation, and condensation

Excited-state nickel-catalyzed C–N cross-coupling of aryl bromides with sodium azide enables the synthesis of diarylamines and primary anilines under mild reaction conditions. The oxidative addition of electron-rich aryl bromides with low-valent Ni under the photochemical conditions is endothermic. Herein, we demonstrate a light-mediated nickel-catalyzed reaction of electronically rich aryl bromides that
