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

A composition for preparing a charge-transport film is provided. The composition comprises, at least: a charge-transporting compound having an ionization potential of between 4.5 and 5.5 ev; and an ionic compound selected from the group consisting of the compounds of formulae (1)-(3),; wherein R¹¹, R²¹ and R³¹ are each independently an organic group bound to A¹-A³, via a carbon atom; R¹², R²², R²³ and R³²-R³⁴ are each independently an arbitrary group. Two or more neighboring groups of R¹¹-R³⁴ may combine to form a ring. A¹-A³ are each an element of the third and subsequent periods in the periodic table. A¹ is an element of group 17 of the long form periodic table; A² is an element of group 16 and A³ is an element of group 15. Z₁ⁿ¹⁻-Z₃ⁿ³⁻ are counter anions and n1-n3 are an ionic valency of the counter anion.
