COMPOSITION FOR CHARGE-TRANSPORTING FILM AND ION COMPOUND, CHARGE-TRANSPORTING FILM AND ORGANIC ELECTROLUMINESCENT DEVICE USING SAME, AND METHOD FOR MANUFACTURING ORGANIC ELECTROLUMINESCENT DEVICE AND METHOD FOR PRODUCING CHARGE-TRANSPORTING 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, (R11-A1+-R12)n1Z1n1−  (1) wherein in general formula (1): R11 represents an organic group bound to A1 via a carbon atom; R12 represents an arbitrary group; R11 and R12 may combine together to form a ring; A1 represents an element belonging to the third and subsequent periods and group 17 of the long form periodic table; Z1n1− represents a counter anion; and n1 represents an ionic valency of the counter anion.
