Abstract
New electroluminescent materials, 4,4′-bis(2-naphthyl-4-tert-butylphenylamino)stilbene (1), 4,4′-bis(4-tert-butylphenyl-3,5-di-tert-butylphenylamino)stilbene (2), and 4,4′-bis(di-4-tert-butylphenylamino)stilbene (3) were synthesized and characterized. To evaluate the electroluminescent properties of these compounds, multilayered OLED devices 1-3 were designed. By employing blue dopant 1 into a multilayer device, it was possible to achieve a maximum luminance of 8861 cd m−2 at 12.0 V, a luminous efficiency of 6.82 cd A−1 at 20 mA cm−2, a power efficiency of 2.72 lm W−1 at 20 mA cm−2, and CIE x,y coordinates of (x = 0.158,y = 0.187) at 10.0 V. These results demonstrated the superiority of these bis(diarylamino)stilbene derivatives in organic light-emitting devices.
