Organic electronic material, ink composition, and organic electronic element

摘要

Provided is an organic electronic material which is excellent in storage stability in the case as an ink composition, and able to prepare, at a high yield, an organic electronic element capable of reducing the driving voltage and of being driven stably for a long period of time, and an ink composition including the organic electronic material. The organic electronic material is characterized in that it contains at least an ionic compound represented by the following general formula (1), and a compound including a charge transporting unit, and the ink composition including the material. In the general formula (1), Ra to Rc each independently represent a hydrogen atom (H), an alkyl group, or a benzyl group. A represents an anion.;
