A series of bipolar anthracene derivatives containing pyridine as an electron withdrawing group and cabazole, triphenylamine and indole as electron donating groups were synthesized and characterized. Particularly, Device E, 9-(4'-(10-(pyridin-2-yl) anthracen-9-yl)biphenyl-4-yl)-9H-carbazol exhibits a high-efficient deep-blue EL emission with the luminous efficiency (LE) of 2.31 cd/A, power efficiency (PE) of 1.39 lm/W and quantum efficiency (QE) of 1.94% at 500 nit. This compound shows the maximum wavelength of the electroluminescence (EL) at 467 nm and the CIE x, y coordinates of (0.16, 0.14) at 6 V.
