Composition for Charge-Transport Film and Ionic Compound, Charge-Transport Film and Organic Electroluminescence Device Using the Same, and Production Method of the Organic Electruminescence Device and Production Method of the Charge-Transport Film

摘要

An excellent composition for a charge-transport film, which can be used to produce an organic electroluminescence device having excellent heat-resistant property, high hole injection/transport capacity and capable of functioning at a low voltage, is proposed. It comprises at least an ionic compound expressed by the following general formula (1) or the like and a charge-transporting compound,
wherein in general formula (1):
R 11 represents an organic group bound to A 1 via a carbon atom; R 12 represents an arbitrary group; R 11 and R 12 may combine together to form a ring;
A 1 represents an element belonging to the third and subsequent periods and group 17 of the long form periodic table;
Z 1 n1- represents a counter anion; and
n 1 represents an ionic valency of the counter anion.
