DEVICE AND METHOD FOR THE PRODUCTION OF COMPOUNDS BY PRECIPITATION
The invention relates to a device and a method for the production of compounds by precipitation of solids from solutions, the physical and chemical properties of the solid particles formed on precipitation being flexible and can be independently fixable. Custom products can thus be produced with very high space-time yields and a particulate nickel/cobalt mixed hydroxide of formula NixCo1-x(OH)2, with a BET surface area of 20 m2/g and a tap density of greater than 2.4 g/cm3.
The invention relates to electroluminescent light-emitting devices, characterized in that they contain at least one conductive polymer layer as electrode, thereby preventing an extended use of a transparent oxide or a metal layer. The combination of said layer with a doped thin layer made of oligomers (small-molecules) is particularly advantageous. According to the invention, the construction of organic electroluminescent light-emitting devices is considerably simplified, and the production process can be performed in a more efficient manner. A feature of the invention is the utilization of the high conductivity of the polymer layer and the extraordinary smoothing properties of the polymer/oligomer combination as a functional layer. Due to the high transparency, the layer combination can be used as an electrode in an organic light diode or as a separately contactable intermediate electrode in a pile of organic materials. Due to the good interface properties, this functional layer has a considerable advantage over other formulations with regard to increased efficiency and service life.

PROCESS FOR PRODUCING AQUEOUS DISPERSION OF COMPOSITE OF POLY(3,4-DIALKOXYTHIOPHENE) WITH POLYANION
A process for producing an aqueous dispersion which contains a conductive polymer ingredient and is capable of forming a thin conductive film excellent in transparency and conductivity; and an aqueous dispersion obtained by the process. The process comprises a step in which a 3,4-dialkoxythiophene is polymerized in an aqueous medium in the presence of a polyanion with the aid of an oxidizing agent. In this step, the oxidizing agent is added by dropping a solution or dispersion of the oxidizing agent into the reaction mixture. Alternatively, the concentration of alkali metal ions in the reaction mixture in the polymerization step is kept at 400 ppm or lower.
