An aromatic amine derivative represented by the following formula (1):
wherein A1 is a substituted or unsubstituted alkyl group, a substituted or unsubstituted aromatic group, a substituted or unsubstituted heterocyclic group or an organic group represented by the following formula (2):
wherein X1, X2 and X3 are independently a substituted or unsubstituted aromatic group or a substituted or unsubstituted heterocyclic group;
X1 and X2 are linkage groups which are different from each other; and
B1, B2 and B3 are independently a substituted or unsubstituted aromatic group or a substituted or unsubstituted heterocyclic group.
derivatives exhibited deep blue emission in toluene solution and thin film. Their electroluminescent performances was investigated by fabricating non-dopedorganiclight-emittingdiodes (OLEDs), exhibiting deep-blue emission with peaks at 444, 440 and 448 nm. The device performance based on pCzAnN as the emitter achieved a low turn-on voltage of 3.3 V, external quantum efficiency of 6.0%, deep-blue emission
