In this study, two anthracene derivatives with quinoline moieties were synthesized. To investigate their electroluminescent (EL) properties, multilayered OLEDs with the following sequence; indiumtin-oxide (ITO)/N, N'-di(1-naphthyl)-N, N'-diphenyl-(1,1'-biphenyl)-4,4'-diamine (NPB) (20 nm)/Blue emitting materials (30 nm)/bathophenanthroline (Bphen) (30 nm)/lithium quinolate (Liq) (2 nm)/Al (100 nm) were fabricated using these materials as emitters. Two devices exhibited EL in blue to sky-blue regions. Especially, a device using 2,3-diphenyl-6-(10-(naphthalen-7-yl)anthracen-9-yl)quinoline (1) as an emitting material exhibited blue emission with a luminous efficiency, a power efficiency, an external quantum efficiency, and Commission International de L'Eclairage (CIE) coordinates of 1.01 cd/A, 0.43 lm/W, 0.80% at 20 mA/cm2, and (0.17, 0.22) at 6.0 V, respectively.
在本研究中，合成了两种带有喹啉部分的蒽衍生物。为了研究它们的电致发光（EL）特性，制备了具有以下结构的多层有机发光二极管；氧化铟锡（ITO）/N，N'-二（1-萘基）-N，N'-二苯基-（1,1'-联苯）-4,4'-二胺（NPB）（20纳米）/蓝色发光材料（30纳米）/红菲绕啉（Bphen）（30纳米）/喹啉酸锂（Liq）（2纳米）/铝（100纳米），使用这些材料作为发光体。两个器件在蓝色到天蓝色区域均表现出电致发光。特别地，一个使用2,3-二苯基-6-（10-（萘-7-基）蒽-9-基）喹啉（1）作为发光材料的器件在20毫安/平方厘米时表现出蓝色发射，其发光效率、功率效率、外量子效率以及国际照明委员会（CIE）坐标分别为1.01坎德拉/安培、0.43流明/瓦、0.80%，在6.0伏时为（0.17, 0.22）。
