Abstract: 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.
