Organic electroluminescent molecules
Résumé
The subject of the present invention is compounds of formula (I): in which Ar 1 and Ar 2 , which are identical or different, denote a monocyclic or polycyclic, optionally substituted, C 6 -C 14 aromatic or C 1 -C 10 heteroaromatic group, Ar 3 denotes an optionally substituted 5-membered C 1 -C 4 heteroaromatic group, and also the use of these compounds in an organic electroluminescent device. It also targets a process for preparing compounds of formula (II'), in which, especially, R denotes an acyclic, monocyclic or polycyclic C 1 -C 20 group comprising at least one nitrogen atom, in particular starting from an abovementioned compound of formula (I).
