    摘要: A specific bis(diarylamino)arylene compound expressed in the following general formula [1.1] is used as a constituent material of an organic EL device. By this, luminescent brilliance and EL property are improved, and further, reduction in luminescent property is suppressed, and durability is improved. (wherein, Ar1 represents a substituted or unsubstituted arylene group having 5 to 42 carbon atoms: at least one of Ar2 to Ar3 independently represents a group expressed in the following general formula [1.2]; and the remaining group(s) of Ar2 to Ar5 independently represents an aryl group having 6 to 20 carbon atoms, and at least one of Ar2 to Ar5 has at least one hydrocarbon group which may include oxygen atom(s).) (wherein, each of R1 to R11 independently represents a hydrogen atom or a substituent.)
