ORGANIC ELECTROLUMINESCENT ELEMENT

摘要

An organic EL element comprising an anode, a cathode, and one or more organic compound layers sandwiched therebetween, wherein at least one of the organic compound layers comprises an organic compound represented by chemical formula (1), specifically any of the chemical formulae (2), (3), (4) and (5). By incorporating desired substituents as R1 to R4, the compound can be made to have one or more of a hole-transporting function, luminescent function, and electron-transporting function. Since the molecule is apt to be nonplanner because of its structure, the compound is less apt to crystallize and has a high glass transition temperature. Therefore, when used in an organic EL element, the compound contributes to an improvement in element life.
