A novel blue light emitting material, 9,10 bis(9,9 diphenylfluorenyl) anthracene(DPFA) was synthesized and it′s optoelectronic properties were studied. Organic light emitting diodes(OLEDs) has been fabricated and showed efficient blue emission at 445 nm with excellent color purity. The brightness of the device is up to 2 433 cd/cm 2 with a high luminescence efficiency of 3 53 cd/A(3 26 lm/W).
