合成并采用DPVB作为发光层,Al/LiF双层电极作阴极,得到了高亮度(>9 800 cd/m2)、高效率(1.7 lm/W)的蓝色有机电致发光器件.“,”1,4-Bis(2,2-diphenylvinyl) benzene(DPVB) was synthesized. A blue organic electroluminescent (EL) device with high brightness (9 800 cd/m2) and efficiency(1.7 lm/W) was obtained by using an Al/LiF bilayer electrode as cathode and using DPVB as emitting layer.
