Organic EL devices and production process thereof
An organic electroluminescent device comprising a light-emitting layer between a pair of electrodes, the light-emitting layer comprising a mixture of a hole-transporting material consisting of a tertiary amine compound, an electron-transporting material and a light-emitting additive material, in which the tertiary amine compound has two or more oxidation potentials determined by a cyclic voltammetry wherein a potential difference between the first oxidation potential and the second oxidation potential in the oxidation potentials is 0.22V or more, and a glass transition temperature of at least 100° C., and the electron-transporting material has a glass transition temperature of at least 100° C.

Oligomerization of aromatic tertiary amines
The oligomerization of some tertiary aromatic amines was studied using ferric chloride in a variety of solvent. The predominant dimer formation of triphenylamine (TPA) was observed in chloroform at O °C where concentration of TPA was 0.125 mmol/l and the molar ratio of ferric chloride to TPA was 4. Except for N-methyldiphenylamine, high molecular weight oligomers were formed in a variety of solvents.
