Synthetic example 1

[0239] (Synthesis of Low Molecular Compound A)

[0240]

[0241] Under a nitrogen atmosphere, 100 g (0.65 mol) of trifluoromethanesulfonic acid was added, followed by stirring at room temperature. A solution obtained by dissolving 61.93 g (0.33 mol) of 4-bromobenzonitrile in 851 ml of dehydrated chloroform was added dropwise to the obtained reaction liquid. The obtained solution was heated up to 95° C., stirred while heating, then cooled to room temperature, and dilute ammonia solution was added thereto under an ice-water bath. The obtained solid was removed by filtration, washed with water and then with diethyl ether, and dried under reduced pressure to obtain 47.8 g of white crystals.

[0242]

[0243] Under a nitrogen atmosphere, 8.06 g (14.65 mmol) of white crystals obtained, 9.15 g (49.84 mmol) of 4-tert-butylphenylboronic acid, Pd (PPh 3 ) 4 1.54 g (1.32 mmol), 500 ml of toluene previously bubbled with nitrogen, and 47.3 ml of ethanol previously bubbled with ni...

Abstract

A composition which contains a compound represented by general formula (1) or a compound having a residue of a compound represented by general formula (1) and a compound represented by general formula (2) or a compound having a residue of a compound represented by general formula (2). In general formula (1), Ar is aryl or a monovalent heterocyclic group. In general formula (2), one of Z1 to Z3 is -N= and the others are -C(R')=; Z4 and Z5 are -C(R')=; one of R6 to Z8 is -N= and the others are -C(R')=; Z9 and Z10 are -C(R')=; and R' is a substituent such as hydrogen, alkyl, alkoxy, aryl, or aryloxy.

Description

technical field [0001] The present invention relates to a composition containing a nitrogen-containing heterocyclic compound and an organic electroluminescent device using the composition. Background technique [0002] In recent years, organic electroluminescent displays using organic electroluminescent elements have attracted attention as next-generation displays. The organic electroluminescent device includes organic layers such as a light emitting layer and a charge transport layer. Furthermore, the above-mentioned organic layer is required to be an organic material having excellent electron-injecting property, and as an example thereof, pertriazine derivatives have been proposed (JP-A-8-119163 and JP-A-2007-137829). [0003] However, when only the triazine derivative is used for the above-mentioned organic layer, the luminance half-life of the obtained organic electroluminescence device may not necessarily be long. Contents of the invention [0004] The object of the...
