Abstract: The invention provides a 1,3,5-tris(diarylamino)benzene represented by the general formula (I) wherein A and B are each independently a group represented by the general formula (II) in which R is a hydrogen atom, an alkyl group of 1-6 carbons or a cycloalkyl group of 5 or 6 carbons and n is 0, 1, 2 or 3, provided that the values of n of A and B are not the same to each other. Such a 1,3,5-tris(diarylamino)benzene is able to form an amorphous film by vacuum evaporation at a relatively low temperature with almost or substantially no thermal decomposition, and is preferably used as organo-electronic functional material, in particular, as a hole injecting agent or a hole transporting agent.
