PREPARING METHOD FOR ORGANIC THIN LAYER OF ORGANIC LIGHT EMITTING DEVICES USING ELECTROCHEMICAL DEPOSITION

摘要

This invention provides a method for preparing an organic thin layer of organic light emitting device using electrochemical deposition and in particular, there is provided a method for preparing an organic thin layer of organic light emitting device comprising one or more organic thin layers between anode and cathode, characterized in that the organic thin layer is formed by electrochemical deposition of a compound having bis(phenylcarbazol) group in molecule. The method for preparation of the organic thin layers of OLED devices in accordance with the invention has simple process by virtue of the use of monomolecular compounds that are easily purchased and prepared, has high productivity, makes it easy to control the thickness of thin layers to be prepared and has excellent adhesion to substrates and further, fundamentally improves erosion that may occur in a firstly-formed organic thin layer during the process of formation of a second organic thin layer especially when two or more organic thin layers are to be prepared in OLED devices and has excellent morphology stability.
