Nickel-Catalyzed N-Arylation Using N -Trimethylsilyl-carbazole

Nickel-catalyzed N-arylation reaction of N -trimethylsilyl-carbazole using aryl bromides is found to proceed in the presence of sodium acetate, giving N -aryl-carbazoles in high yields. Under these conditions, N -trimethylsilyl-carbazole could react with aryl bromides selectively even in the presence of other N -trimethylsilyl-amines or N -H-amines. This arylation reaction was applied to the polymerization to provide a polycarbazole.

Buchwald–Hartwig Amination of Nitroarenes

The Buchwald–Hartwig amination of nitroarenes was achieved for the first time by using palladium catalysts bearing dialkyl(biaryl)phosphine ligands. These cross-coupling reactions of nitroarenes with diarylamines, arylamines, and alkylamines afforded the corresponding substituted arylamines. A catalytic cycle involving the oxidative addition of the Ar?NO2 bond to palladium(0) followed by nitrite/amine exchange is proposed based on a stoichiometric reaction.

Electrochemically fabricated electrochromic films from 4-(: N -carbazolyl)triphenylamine and its dimethoxy derivative

A carbazolyl-substituted triphenylamine derivative, 4-(N-carbazolyl)triphenylamine (TPACz), was synthesized and used to build a fluorescent and electrochromic polymeric film (PTPACz) on the ITO-glass surface by electrochemical oxidative coupling reactions

AROMATIC AMINE DERIVATIVE, AND ORGANIC ELECTROLUMINESCENT ELEMENT

Provided are an organic electroluminescence device that not only provides high efficiency but also has a long lifetime, and an aromatic amine derivative that realizes the device. The organic electroluminescence device includes an aromatic amine derivative, including at least one substituent A having dibenzofuran and at least one substituent B selected from groups each having dibenzofuran or carbazole, in a molecule thereof, in which the substituent A and the substituent B include groups different from each other, and the substituent A and the substituent B are bonded to the same nitrogen atom, or different nitrogen atoms, in the molecule. The molecules of the aromatic amine derivative hardly crystallize, which improves a yield in the production of the organic electroluminescence device. In the organic electroluminescence device, including an organic thin film layer formed of one or more layers including at least a light emitting layer, the organic thin film layer being interposed between a cathode and an anode, the aromatic amine derivative is contained in at least one layer, particularly a hole transport layer, in the organic thin film layer.
