Abstract:
An object of the present invention is to provide an organic electronic material that can be easily formed into a multilayer structure. A further object of the present invention is to provide an organic electronic device and an organic EL device that exhibit a better emission efficiency and a better emission lifetime than heretofore achieved. In order to achieve these objects, an organic electronic material is provided, the material includes a polymer or oligomer that has at least one polymerizable substituent and a hole-transporting repeat unit.
