A series of bipolar anthracene derivatives containing triphenylamine as an electron donating group and pyridine, quinoline, isoquinoline and benzothiazole as electron withdrawing groups were synthesized and characterized. Particularly, a material, 9-quinolinyl-10-triphenylamin anthracene (3) exhibits a highly efficient sky-blue EL emission with the luminous efficiency (LE) of 9.36 cd/A, power efficiency (PE) of 5.94 lm/W and quantum efficiency (QE) of 4.23% at 500 nit. This material shows the maximum wavelength of the electroluminescence (EL) at 486 nm and the CIE x, y coordinates of (0.17, 0.36) at 6 V.
