Organic Light Emitting Dioides (OLED)devices were fabricated with blue emission based on azatrioxacirculene and 4,4-N,N′-Dicarbazolyl-1,1′-biphenyl (CBP) with maximum brightness of 840 kd/m2 at 12 V and the starting voltage of 3.5 V. The vibronic emission spectrum was analyzed by the promotive modes calculation method. The electroluminescence of fabricated OLED device is caused by the 0-0 electronic transition and single excitations of 1473 cm−1 and 1673 cm−1 modes and combinations thereof.
