COMPOUND WITH TRIPHENYLAMINE STRUCTURE, AND ORGANIC ELECTROLUMINESCENT ELEMENT

摘要

Problem to Be Solved: There is provided an organic compound of excellent characteristics that exhibits excellent hole-injecting/transporting performance and has an electron blocking ability and a highly stable thin-film state with excellent heat resistance. The compound is provided as a material of a high-efficiency, high-durability organic EL device, and is used to provide a high-efficiency, high-durability organic EL device. Solution: The compound of the present invention is an arylamine compound of general formula (1) or (2) having a triphenylamine structure. The arylamine compound is used as a constituent material of at least one organic layer in an organic electroluminescent device that includes a pair of electrodes, and one or more organic layers sandwiched between the pair of electrodes.
