The invention concerns electroluminescent arrangements composed of a substrate, an anode, an electroluminescent element and a cathode, at least one of the two electrodes being transparent in the visible spectrum range. The electroluminescent electrode can contain the following components in sequence: an electroluminescent, holeinjecting, holetransporting zone, an electrontransporting zone and an electron-injecting zone. The invention is characterized in that the holeinjecting and holetransporting zone contains an optionally substituted tris 1,3,5(aminophenyl) benzene compound A or a mixture thereof, and the electroluminescent element optionally contains a further functionalized compound selected from the group comprising holetransporting materials, a luminescent material B and optionally electrontransporting materials. In addition to component A, the holeinjecting and holetransporting zone can comprise one a plurality of further holetransporting compounds. At least one zone is present, individual zones can be omitted and the zone (s) present can assume a plurality of functions.
