Abstract: In this research, we designed and synthesized three blue fluorescent materials?based on anthracene derivatives containing electron-withdrawing heteroaromatics. To investigate electroluminescent properties of these blue emitting compounds, devices were fabricated as following structure : indium tin oxide (ITO) (180 nm) / N,N'-diphenyl-N,N'-(1-napthyl)-(1,1'-phenyl)-4,4'-diamine (NPB) (20 nm) / emitting materials (30 nm) / bathophenanthroline (Bphen) (30 nm) / lithium quinolate (Liq) (2 nm) / Al (100 nm). Particularly, a device using 2,3-diphenyl-6-[10-(naphthalen-7-yl)anthracen-9-yl]quinoline?as emitter showed good EL properties with power efficiency and luminous efficiency of 0.63 lm/W and 1.02 cd/A, at 100 cd/m2, respectively. The CIE coordinates of this device was (0.17, 0.22) at 6.0 V.
