摘要： An organic electronic material containing a charge transport polymer that includes a 9-phenylcarbazole moiety, and also includes a structure branched in at least three directions from the 9-phenylcarbazole moiety, wherein the organic electronic material satisfies at least one of (I) or (II) below. (I) The 9-phenylcarbazole moiety has a hydrogen atom at position 4 of the phenyl group of the 9-phenylcarbazole moiety. (II) The charge transport polymer also has a triphenylamine structure in which at least one phenyl group has an alkoxy group.
