ORGANIC ELECTRONIC MATERIAL, INK COMPOSITION CONTAINING THE SAME, AND ORGANIC THIN FILM, ORGANIC ELECTRONIC ELEMENT, ORGANIC ELECTROLUMINESCENT ELEMENT, LIGHTING DEVICE, AND DISPLAY DEVICE FORMED USING THE ORGANIC ELECTRONIC MATERIAL AND THE INK COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide: an organic electronic material that can be easily multilayered, and also can be used in even a substrate, such as a resin, that cannot be processed at high temperatures; an ink composition containing the organic electronic material; an organic thin film formed using the organic electronic material or the ink composition; and an organic electronic element and an organic EL element which are formed using the organic thin film and have more excellent luminous efficiency and emission lifetime than conventional ones.SOLUTION: There are provided: an organic electronic material that is characterized by containing an oligomer or a polymer having a structure that branches into three or more directions and having at least one polymerizable substituent; an ink composition containing the organic electronic material; an organic thin film prepared using the organic electronic material; and an organic electronic element and an organic electroluminescent element including the organic thin film.
