Title:
ARYLDIAMINE COMPOUND AND ORGANIC ELECTROLUMINESCENT ELEMENT
Document Type and Number:
WIPO Patent Application WO/2018/047899
Kind Code:
A1
Abstract:
According to the present invention, an aryldiamine compound represented by general formula (1) and an organic electroluminescent element comprising a pair of electrodes and at least one organic layer sandwiched between the electrodes are provided, wherein the organic electroluminescent element is characterized in that the aryldiamine compound is used as a constituent material for the at least one organic layer. The aryldiamine compound according to the present invention is superior in hole-transporting properties, hole injection properties, electron stopping properties, stability when formed into a thin film, and heat resistance. The electroluminescent element according to the present invention has a high luminous efficiency, a high power efficiency and a low driving voltage, and particularly has a long service life.
