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.
