ORGANIC COMPOUNDS, LIGHE EMITTING DIODE AND LIGHT EMITTING DEVICE HAVING THE COMPOUNDS

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

One-pot synthesis of 1, 2-disubstituted 4-, 5-, 6-, and 7-azaindoles from amino-o-halopyridines via n-arylation/sonogashira/cyclization reaction

A direct synthesis of several 1, 2-disubstituted 4-, 5-, 6-, and 7-azaindoles from available amino-o-halopyridines is described. This procedure involves a palladium-catalyzed N-arylation followed by a Sonogashira reaction and subsequent cyclization in a one-pot manner, exhibiting a wide scope and compatibility with electron-withdrawing and electron-donating groups. The strategy represents an advancement in azaindole chemistry with a straightforward approach toward 1, 2-disubstituted azaindoles, while avoiding complex N-arylations of hindered 2-substituted azaindoles and difficult purification steps of intermediates.

Inverting Conventional Chemoselectivity in Pd-Catalyzed Amine Arylations with Multiply Halogenated Pyridines

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.

Synthesis of Substituted 4-, 5-, 6-, and 7-Azaindoles from Aminopyridines via a Cascade C-N Cross-Coupling/Heck Reaction

A practical palladium-catalyzed cascade C-N cross-coupling/Heck reaction of alkenyl bromides with amino-o-bromopyridines is described for a straightforward synthesis of substituted 4-, 5-, 6-, and 7-azaindoles using a Pd2(dba)3/XPhos/t-BuONa system. This procedure consists of the first cascade C-N cross-coupling/Heck approach toward all four azaindole isomers from available aminopyridines. The scope of the reaction was investigated and several alkenyl bromides were used, allowing access to different substituted azaindoles. This protocol was further explored for N-substituted amino-o-bromopyridines.

Effect of the position of nitrogen in pyridoindole on photophysical properties and device performances of α-, β-, γ-carboline based high triplet energy host materials for deep blue devices

Three carboline derivatives with nitrogen at different positions of the pyridoindole unit were synthesized and the effect of the position of nitrogen on the photophysical properties and device performances was investigated. β-Carboline was effective in obtaining high triplet energy and stabilizing energy levels, while α-carboline was better than other carbolines in terms of quantum efficiency. However, γ-carboline could not stabilize the LUMO level and low quantum efficiency was obtained.

One-pot synthesis of α-carbolines via sequential palladium-catalyzed aryl amination and intramolecular arylation

A one-pot synthesis of α-carbolines via a palladium-catalyzed aryl amination followed by intramolecular arylation is described. 2,3-Dichloro- and 2,3-dibromopyridines have been shown to react with readily available anilines to obtain various substituted α-carbolines in moderate to excellent yields.

γ-Carboline derivatives with anti-bovine viral diarrhea virus (BVDV) activity

Based on anti-viral screening of our heteroaromatics derived from thalidomide, the γ-carboline skeleton has been identified as a superior scaffold structure for compounds with potent anti-bovine viral diarrhea virus (BVDV) activity. Structural development studies led to a potent anti-viral agent, SK5M (5-methyl-γ-carboline), with the EC50 of 0.26 μM.
