Abstract of Disclosure
The invention relates to an electroluminescent device, in which the luminescent layer contains a luminescent compound and a compound of the general formula I as doping agent, wherein B is an unsaturated carbocyclic or heterocyclic 4-8-link ring, which can also contain an alicyclic bridge, the rings D and E are five- or six-link rings, which each can contain one more hetero-atom N, O and S, the radicals R are one or more substituents H or straight-chain or branched C
