摘要 |
An object of the present invention to provide a material for a light-emitting element or a hole injecting high molecular weight material which has a sufficient hole injecting property, without using a dopant having an electron accepting property. One of materials of the present invention which can achieve the object, has a repeating unit represented by the following formula (1), In the formula (1), R1 represents hydrogen, an alkyl group, a cyano group, or an alkoxy group, and R2 represents an aryl group. The material has an ionization potential of 4.9 eV or more and 5.4 eV or less.
