Solution processes for fabricating an optoelectronic devices include contacting an electroluminescent layer comprising an alcohol-insoluble electroluminescent polymer with an alcoholic solution of a compound of formula Ia to form an electron transporting layer directly disposed on the electroluminescent layer; and depositing a metal cathode layer on the electron transporting layer; wherein R 1 is, independently at each occurrence, C 1-20 hydrocarbyl; at least one of R 1 is R 3 ; R 2 is independently at each occurrence hydrogen, C 1-20 hydrocarbyl, C 1-20 hydrocarbyloxy, C 1-20 thioether, C 1-20 hydrocarbylcarbonyloxy or cyano; R 3 is C 1-20 hydrocarbyl containing at least one S, N, O or P atom between carbon atoms; a is independently at each occurrence 0, 1 or 2; and n is 0 or 1.

Aromatic amine derivative and organic electroluminescent device using the same

Provided are: an aromatic amine derivative in which a terminal substituent such as a dibenzofuran ring or a dibenzothiophene ring is bonded to a nitrogen atom directly or through an arylene group or the like; an organic electroluminescence device including an organic thin film layer formed of one or more layers including a light emitting layer and interposed between a cathode and an anode in which a layer of the organic thin film layer contains the aromatic amine derivative by itself or as a component of a mixture, and the device has a long lifetime and high luminous efficiency; and an aromatic amine derivative for realizing the device.
