A new red fluorescent material, (2Z,2'Z)-3,3'-[4,4 ''-bis(dimethylamino)-1,1':4',1 ''-terphenyl-2',5'-diyl]bis(2-phenylacrylonitrile) (ABCV-P), preventing concentration quenching in solid state was synthesized. Studies on the device performance of ABCV-P doped OLEDs with variation of the doping concentration and thickness of the emitting layer as well as the optical properties of ABCV-P were carried out. The effective doping concentration of ABCV-P dopant was in the range of 40%-50%. ABCV-P doped OLEDs showed maximum luminance of 11000 cd/m(2) (40%) and 6800cd/m(2) (50%), CIExy coordinates of (0.588, 0.410) (40%) and (0.597, 0.402) (50%) and full width at half maxima of 71 nm and 72.5 nm, respectively. Accordingly, ABCV-P doped OLED showed much lower sensitivity to doping concentration than the typical red doped ones.
