Organic electronic material, ink composition, and organic electronic element

摘要

Provided is an organic electronic material which is excellent in curability at low temperatures in the case as an ink composition, and able to prepare an organic electronic element capable of reducing the driving voltage and of being driven stably for a long time. The organic electronic material is characterized by containing at least an ionic compound represented by the following general formula (1), and a compound including a charge transporting unit. [In the general formula (1), Ar represents an aryl group or a heteroaryl group, Ra to Rb each independently represent a hydrogen atom (H), an alkyl group, a benzyl group, an aryl group, or a heteroaryl group, and Ar, Ra and Rb may be linked to each other to form a ring. However, at least one of Ra to Rb is any of a hydrogen atom, an alkyl group, and a benzyl group. A represents an anion.];
