摘　　要：详细叙述了利用9-溴蒽为原料制备高纯蓝色有机发光材料9,9′-联二蒽的方法,在研究了此材料和黄光染料Rubrene发光特性的基础上,采用高效的荧光染料Rubrene作为掺杂剂掺杂在母体材料9,9′-联蒽中,制备了单发光层结构的有机电致发光器件。当掺杂摩尔分数为1.0%,驱动电压为12V时,器件得到了近白色发光(色坐标x=0.328,y=0.342)。在驱动电压为23V时,器件的亮度达到了7843cd/m2,在驱动电压为13V时,器件的效率达到了3.45cd/A。In the paper,the method of synthesizing the high pure 9,9′-bianthracene with the raw material 9,9′- moanthraeene has been discussed in detail. Study the luminescence characteristic of Rubrene and 9,9′-bianthracene,which is synthesized and purified by ourselves. Single luminescence layer OLEDs with 9,9′bianthracene doped by Rubrene with different mol fractions are fabricated . While the proportion of Rubrene is 1.0 % and the driving voltage is 12V, the commission international de L＇-eclairage（CIE） coordinate of device is x=0. 328 and y=0. 342. The driving voltage is about 23V, the luminescence brightness of the OLEDs reach 7843cd/m^2. When the voltage is 13V,the maximum efficiency is 3.45cd/A.
