- NOVEL CATHODE BUFFER LAYER MATERIAL AND ORGANIC PHOTOELECTRIC DEVICE INCLUDING SAME
-
The present invention relates to a novel cathode buffer layer material and an organic photoelectric device including the same. When the novel compound of the present invention is applied to a cathode buffer layer of an organic photoelectric device, for example, an organic solar cell or an organic photodiode, there is an effect in which the surface characteristics of an electron transport layer are improved through the high dipole moment of the novel compound to thereby facilitate electron extraction from a photoactive layer to a cathode electrode and to reduce series resistance and leakage current, and accordingly, the performance of an organic optoelectronic device (organic solar cell, organic photodiode, etc.) to be manufactured can be remarkably improved, which is industrially advantageous.

- Iridium-Catalyzed Alkylation of Amine and Nitrobenzene with Alcohol to Tertiary Amine under Base- and Solvent-Free Conditions
-
Herein, an efficient and green method for the selective synthesis of tertiary amines has been developed that involves iridium-catalyzed alkylation of various primary amines with aromatic or aliphatic alcohols. Notably, the catalytic protocol enables this transformation in the absence of additional base and solvent. Furthermore, the alkylation of nitrobenzene with primary alcohol to tertiary amine has also been achieved by the same catalytic system. Deuterium-labeling experiments and a series of control experiments were conducted, and the results suggested that an intermolecular borrowing hydrogen pathway might exist in the alkylation process.

- Method of producing higher amine (by machine translation)
-
PROBLEM TO BE SOLVED: To provide a method of producing a secondary or tertiary higher amine. SOLUTION: The method of producing a higher amine comprises allowing a primary or secondary amine to react with an alcohol in the presence of at least one species of hydrogen halide selected from hydrogen chloride, hydrogen bromide and hydrogen iodide, or in the presence of a compound capable of producing a hydrogen halide (such as 1,3,5-triazo-2,4,6-triphosphorine-2,2,4,4,6,6-chloride). If the raw material amine is a primary amine, a secondary higher amine and a tertiary higher amine can be produced. If the raw material amine is a secondary amine, a tertiary higher amine can be produced. COPYRIGHT: (C)2012,JPO&INPIT

- Catalytic N-Alkylation of Amines Using Carboxylic Acids and Molecular Hydrogen
-
A convenient, practical and green N-alkylation of amines has been accomplished by applying readily available carboxylic acids in the presence of molecular hydrogen. Applying an in situ formed ruthenium/triphos complex and an organic acid as cocatalyst, a broad range of alkylated secondary and tertiary amines are obtained in good to excellent yields. This novel method is also successfully applied for the synthesis of unsymmetrically substituted N-methyl/alkyl anilines through a direct three-component coupling reaction of the corresponding amines, carboxylic acids, and CO2 as a C1 source.

- Cruciform 9,10-distyryl-2,6-bis(p-dialkylamino-styryl)anthracene homologues exhibiting alkyl length-tunable piezochromic luminescence and heat-recovery temperature of ground states
-
A series of 2,6-bis(p-dialkylaminostyryl)-9,10-distyrylanthracene (FCn) cruciforms with N-alkyl chains of different lengths have been synthesized, and their aggregation-enhanced fluorescence and piezochromic luminescence (PFC) behaviours are investigated. These 9,10-distyrylanthracene-containing cruciforms exhibit relatively low fluorescence quantum yields (Φ) in THF solution (Φ ≈ 10%) and moderate aggregation-enhanced emission in aqueous media (Φ ≈ 25%), but strong and chain length-dependent solid-state fluorescence emission. Grinding and pressing experiments indicate that they are all effective PFC materials in terms of mechanical stress-induced spectral shifts (ΔλPFC = 23-54 nm), moreover, the longer alkyl-containing FCn shows a larger ΔλPFC. Powder X-ray diffraction and differential scanning calorimetry measurements reveal that the transformation between the crystalline and amorphous states upon external stimuli is responsible for the reversible PFC behaviour. It is found that increasing the N-alkyl length could effectively decrease the cold-crystallization temperature of the ground states to render the PFC states with a tunable heat-recovering temperature, and ground FC10 and FC12 solids can recover spontaneously to their original states at room temperature.

- Direct one-pot reductive N-alkylation of nitroarenes by using alcohols with supported gold catalysts
-
Gold standard support! The direct reductive mono- or di-N-alkylation of aromatic nitro compounds with alcohols, using a hydrogen-borrowing strategy, was efficiently promoted by a ligand-free titania-supported gold catalyst system (see scheme). A variety of nitroarenes were selectively converted into the corresponding secondary or tertiary amines in good to excellent yields without any co-catalysts, such as bases and stabilizing ligands.

- Ruthenium-catalyzed tertiary amine formation from nitroarenes and alcohols
-
A highly selective ruthenium-catalyzed C-N bond formation was developed by using the hydrogen-borrowing strategy. Various tertiary amines were obtained efficiently from nitroarenes and primary alcohols. The reaction tolerates a wide range of functionalities. A tentative mechanism was proposed for this direct amination reaction of alcohols with nitroarenes.
