An organic electroluminescent device comprising: a pair of electrodes comprising an anode and a cathode, and one or more layers arranged between the anode and the cathode; wherein at least one of the one or more layers is a light emitting layer and wherein the one or more layers, comprises an organic compound represented by a substituted 2,2′-biimidazole. The substitutents on the biimidazole may be selected form a range of suitable substituents, including: hydrogen, a substituted or unsubstituted heterocyclic group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aralkyl group, a substituted aryl group containing at least one atom selected from the group consisting of N, O, S, Si, P, F, Cl, Br; and/or comprising at least three organic rings, the organic rings being fused or non-fused, or a number of the adjacent substituent sites may together form a substituted or unsubstituted cyclic group; furthermore some substituents may be the same or different and may be selected from the group consisting of: hydrogen, deuterium, a substituted or unsubstituted alkyl group, a halogen atom or a cyano group.
一种有机电致发光器件,包括:一对电极,包括阳极和阴极,以及安排在阳极和阴极之间的一个或多个层;其中,所述一个或多个层中至少有一个是发光层,并且所述一个或多个层包括一种由取代的2,2'-联吡咯表示的有机化合物。联吡咯上的取代基可以选择适当的取代基,包括:氢、取代或未取代的杂环基、取代或未取代的烷基、取代或未取代的芳基烷基、含有来自N、O、S、Si、P、F、Cl、Br的至少一个原子的取代芳基基团和/或包含至少三个有机环的,有机环可以是融合的或非融合的,或者相邻的取代位点的一些数目可以共同形成取代或未取代的环状基团;此外,一些取代基可以相同或不同,并且可以选择来自氢、氘、取代或未取代的烷基、卤原子或氰基的群。
