ABSTRACT:
An organic electroluminescent device comprises a cathode, an anode, and has therebetween a light-emitting layer comprising an emissive component represented by formula (I):wherein:Ar1, each Ar2, and Ar3through Ar7are independently selected aryl or heteroaryl groups, which may contain additional fused rings and provided that two aryl or heteroaryl rings may be joined;n is 1, 2 or 3. The device exhibits good luminous yield with desirable color coordinates, particularly in the blue or blue-green region.
