| Abstract: | A new blue electroluminescent material, distyrylarylene(DSA) derivative, 4,4' bis2,2 (1 naphthyl,phenyl)vinyl] 1,1' biphenyl(NPVBi) is designed and synthesized. The DSA derivative shows better thermal stability because of its high glass transition temperature. A blue organic light emitting diode(OLED) with the structure ITO/TPD/NPVBi/Alq/LiF/Al is studied. The electroluminescent(EL) spectrum of the OLED exhibits that light emission originates from NPVBi with a peak at 460 nm, its Commission Internationale de l'Eclairage(CIE) color coordinates are x=0.16, y=0.15, and showing independence of CIE color coordinates on current density. The new DSA derivative is expectable as a new candidate for blue light emitter in OLEDs. |
