Abstract
Provided are a nitrogen-containing aromatic heterocyclic compound useful as an organic semiconductor material and an organic electronic device using this compound. The nitrogen-containing aromatic heterocyclic compound has a fused indole skeleton represented by the following formula (1), the organic semiconductor material contains the compound, and the organic electronic device uses the organic semiconductor material. In general formula (1), X is N-A', O, S, or Se; A is an alkyl group, a cycloalkyl group, an alkenyl group, an alkynyl group, an aromatic hydrocarbon group, or an aromatic heterocyclic group exclusive of a fused heterocycle consisting of 4 rings or more; and R is a hydrogen atom, an alkyl group, a cycloalkyl group, an alkenyl group, an alkynyl group, an aromatic hydrocarbon group, or an aromatic heterocyclic group exclusive of a fused heterocycle consisting of 4 rings or more.
