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 spectral range and it being possible for the electroluminescent element to contain the following zones: a hole-injecting zone, hole-transporting zone, electroluminescent zone, electron-transporting zone and/or an electron-injecting zone, characterized in that the hole-injecting and/or hole-transporting 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 from the group consisting of the optionally hole-transporting materials, a luminescent material B) or a quinacridone derivative C), it being possible for the hole-injecting and hole-transporting zone to contain one or more further hole-transporting compounds in addition to the component A, at least one zone being present, it being possible for individual zones to be omitted and it being possible for the zone(s) present to perform several functions. |
