AK-1NA and AK-2NA based on dibenzo-diazocine and anthracene moieties were designed and synthesized. Normalized UV-visible spectra of AK-1NA and AK-2NA in film state showed maximum absorption wavelength of 394 and 393 nm. PL spectra of AK-1NA and AK-2NA showed maximum emission wavelength of 429 and 444 nm. At a current density of 10 mA/cm2, OLED devices of AK-1NA and AK-2NA exhibited luminance efficiency of 2.39 and 1.50 cd/A, power efficiency of 1.01 and 0.81 lm/W. Also, OLED devices of AK-1NA and AK-2NA devices exhibited CIE(x, y ) of (0.16, 0.22) and (0.23, 0.42).
