DEVICE MATERIAL FOR HOLE INJECTION/TRANSPORT LAYER, INK FOR FORMING HOLE INJECTION/TRANSPORT LAYER, DEVICE HAVING HOLE INJECTION/TRANSPORT LAYER, AND METHOD FOR MANUFACTURING SAME

摘要

An object of the present invention is to provide a device material for a hole injection transport layer, which has wettability that can be altered by energy irradiation, high process resistance and an excellent hole injecting transporting property and which can form a hole injection transport layer by a solution coating method, and an ink for a hole injection transport layer, which comprises the device material. Another object of the present invention is to provide a device in which a layer to be provided on a hole injection transport layer can be patterned and which can achieve a long life, and a method for producing the device. Disclosed is a device material for a hole injection transport layer, wherein a fluorine-containing organic compound is attached to the surface of a transition metal-containing nanoparticle or nanocluster which contains at least a transition metal oxide. Also disclosed are a device and an ink for a hole injection transport layer, the device and ink comprising the device material each, and a method for producing the device.
