| 中文摘要 | higwy efficient dcjtb-doped device was realized by enhanced electron injection and exciton confinement. a fluorine end-capped linear phenylene/oxadiazole oligomer 2,5-bis(4-fluorobiphenyl-4'-yl)-1,3,4-oxadiazole (1) and a trifluoromethyl end-capped oligomer 2,5-bis(4-trifluoromethylbiphenyl-4'-yl)-1,3,4-oxadiazole (2) were designed and incorporated as an electron transporting/hole blocking material in the device structure ito/npb (60 mn)/dcjtb:alq(3) (0.5%, 10 nm)/1 or 2 (20 nm)/alq(3) (30 mn)/lif (1 nm)/al (100 nm). the devices showed highly efficient red luminescence. in particular, the device based on 1 achieved pure red luminescence at 620 run originating from dcjtb, with a narrow fwhi of 65 nm, maximal brightness of 13,300 cd/m(2) at voltage of 20.8 v and current density of ca. 355 ma/cm(2). high current and power efficiencies (> 3.6 cd/a. 1.01m/w) were retained within a wide range of current densities. our results show efficient and stable dcjtb-doped red electroluminescence could be anticipated for practical applications by taking advantage of the present approaches. the control experiments using bcp were also studied. |
