We describe the electroluminescent properties of blue fluorescent materials based on mono(triphenylamino) anthracene derivatives synthesized via Suzuki cross coupling reactions. To explore the electroluminescent properties of materials 1-3, multilayered OLEDs were fabricated and all devices exhibited efficient blue emissions. Among those, device 1, with CIE x,y coordinates of (0.159, 0.166) at 12.0 V, exhibited the best performance, with a maximum luminance of 7306 cd/m(2) at 12.0 V, and luminous and power efficiencies of 4.95 cd/A and 1.83 lm/W at 20 mA/cm(2), respectively.
