摘要
An object of the present invention is to provide an organic compound that has excellent properties, with excellent hole injection and transport performance, electron blocking capability, and high stability in a thin film state, and furthermore to provide a highly efficient and highly durable organic EL device by using this compound. The present invention relates to a compound having a triarylamine structure and being represented by the structural formula (A-1) below, where A, B, and C may be the same or different, and each represent a group represented by the structural formula (B-1) below, a substituted or unsubstituted aromatic hydrocarbon group, a substituted or unsubstituted aromatic heterocyclic group, or a substituted or unsubstituted fused polycyclic aromatic group, where at least one of A, B, and C is not the group represented by the structural formula (B-1) below. (For the symbols and the like in the formulae, see the descriptions in the specification.)
