AROMATIC AMINE DERIVATIVE, ORGANIC ELECTROLUMINESCENT ELEMENT AND ELECTRONIC DEVICE

摘要

An organic EL element with high efficiency and long life, an electronic device mounting said element, and compound making it possible to provide such an organic electroluminescent element are provided. Said compound is specifically represented in general formula (1). [In formula (1), L1 and L2 are a single-bond, or a substituted or unsubstituted arylene group. R1 and R2 are a hydrogen atom, an alkyl group or an aryl group. At least one of Ar1-Ar4 is a group represented by general formula (2), and those that are not are independently a substituted or unsubstituted aryl group. (R3-R5 are an alkyl group, cycloalkyl group, alkoxy group, aralkyl group, aryloxy group, aryl group, halogen atom or cyano group. R3-R5 may optionally bond to each other to form a hydrocarbon ring. a and b are independently integers 0-4. c is an integer 0-5. Further, if a, b or c is 2 or greater, adjacent R3's, adjacent R4's or adjacent R5's may optionally bond to each other to form a hydrocarbon ring.)]
