| Abstract | We designed and synthesized two pyrene derivatives: 1,6-di-1-naphthalenyl-pyrene (1) 1,6-Bis(10- phenyl-9-anthracenyl)-pyrene (2). Two OLED devices were fabricated in the following sequence: ITO (180 nm)/4,4'-bis(N-(1-naphthyl)-N-phenylamino)bipheny (NPB) (50 nm)/Blue materials 1 and 2 (40 nm)/Tris(8-hydroxyquinolinato)aluminium (Alq3) (15 nm)/lithium quinolate (Liq) (2.0 nm)/Al (100 nm). Two devices showed efficient blue emissions. Particularly, a device using 2 as emitting material showed blue EL properties with luminous efficiencies of 3.19 cd/A, power efficiencies of 1.54 lm/W, quantum efficiency of 2.42% at 500 cd/m2 and CIEx,y coordinates of (0.19, 0.16) at 7 V. |
