New 3,4,5-substituted 1,2,4-triazole derivative useful as charge transfer materials for organic light emitting diodes

摘要

3,4,5-Substituted 1,2,4-triazole derivative (I) is new. 3,4,5-Substituted 1,2,4-triazole derivative of formula (I) is new. R-A, R-B : (hetero)aryl (optionally substituted by alkyl, aryl, dialkylamino, alkoxy, halo or CN); R-G : (hetero)aryl; RxN-phenyl, N-pyridyl or O; Ry1C or N (when Ry1 is N, Rx is O and Rz is replaced by phenyl substitution at the former C-atom); RzCR=CR-CR=CR, N=CR-CR=CR, CR=N-CR=CR, N=CR-N=CR; R : H, F, OCH3, CH3 or CN; and n : 1 or 2. An independent claim is also included for an organic electro luminescence device (A) comprising (I) with pure or doped layers. [Image].
