Organic electronic device and method for producing the same

A method for producing an organic electronic device comprising a substrate, two or more electrodes facing each other disposed on the substrate and at least one organic layer disposed between two electrodes, among the electrodes, comprising the steps of:

• forming a layer containing a reactive organic compound having a reducing portion or a proton accepting, portion between at least one electrode and an organic layer containing a charge injection transporting material;
• producing a radical anion of the charge injection transporting material by a direct reaction of the reducing portion or the proton accepting portion of the reactive organic compound with the charge injection transporting material;
• and
• forming the at least one electrode by (i) a vacuum vapor deposition method using a metal which has a work function of 4.2 eV or more (except a metal which can reduce a metal ion contained in the metallic compound to a metal under vacuum condition), or (ii) a wet film forming method using one or more materials selected from the group consisting of a metallic particle, a metal oxide particle, a metal having a low melting point, an alloy containing a metal having a low melting point and a conductive polymer,
• wherein the reactive organic compound is such that oxygen is not directly bonded to a metal, and is at least one kind of compound selected from the group consisting of a metallic cyclopentadiene compound;
• wherein the metal contained in the metallic cyclopentadiene compound is at least one kind of metal selected from the group consisting of an alkali metal, an alkaline-earth metal, scandium and yttrium.

An organic electronic device comprising a substrate, two or more electrodes facing each other disposed on the substrate and at least one organic layer disposed between two electrodes among the electrodes, wherein at least one electrode and/or an organic layer containing a charge injection transporting material disposed adjacent to the at least one electrode contains a reactive organic compound having a reducing portion or a proton accepting portion and/or a reaction product thereof and the reducing portion or the proton accepting portion of the reactive organic compound directly reacts with the charge injection transporting material to form a radical anion of the charge injection transporting material;

• wherein the reactive organic compound is such that oxygen is not directly bonded to a metal, and is at least one kind of compound selected from the group consisting of a metallic cyclopentadiene compound;
• wherein the metal contained in the metallic cyclopentadiene compound is at least one kind of metal selected from the group consisting of an alkali metal, an alkaline-earth metal, scandium and yttrium;
• and
• wherein the at least one electrode adjacent to the layer containing the reactive organic compound and/or the reaction product thereof is comprised of (i) a vacuum deposited film comprising a metal which has a work function of 4.2 eV or more (except a metal which can reduce a metal ion contained in the metallic compound to a metal under vacuum condition), or (ii) a film formed by a wet film forming method comprising one or more materials selected from the group consisting of a metallic particle, a metal oxide particle, a metal having a low melting point and an alloy containing a metal having a low melting point.
