COMPOSITION FOR CHARGE TRANSPORT MEMBRANE AND IONIC COMPOUND, CHARGE TRANSPORT MEMBRANE AND ORGANIC ELECTROLUMINESCENT DEVICE EACH USING THE SAME, AND METHOD FOR PRODUCING THE DEVICE AND METHOD FOR PRODUCING THE MEMBRANE

摘要

PROBLEM TO BE SOLVED: To provide an excellent composition for charge transport membrane capable of obtaining an organic electroluminescent device having high heat resistance and high positive hole injection and transport ability and drivable at low voltage.;SOLUTION: The composition comprises at least an ionic compound of the general formula(1) or the like and a charge-transporting compound. In the general formula(1), R¹¹ is an organic group bound via a carbon atom to A¹; R¹² is any group; R¹¹ and R¹² may be bound to each other to form a ring; A¹ is an element of the 3rd period or thereafter belonging to group 17 in the long-period-type periodic table; Z₁^n1- is a counteranion; and n₁ is the valence of the counteranion.;COPYRIGHT: (C)2006,JPO&NCIPI
