Abstract

In this study, we designed and synthesized two blue fluorescence materials using phenylanthracenesubstituted-indenoquinoline derivatives by Suzuki coupling reaction for organic light-emitting diodes (OLEDs). In order to study their electroluminescent properties, we fabricated the OLED devices using these two materials as emissive layer (EML) with the following sequence: indium-tin-oxide (ITO, 180 nm)/4,4',4″-tris[2-naphthyl(phenyl)-amino]triphenylamine (2-TNATA, 30 nm)/'-diphenyl-'-(2-napthyl)-(1,1'-phenyl)-4,4'-diamine (NPB, 20 nm)/Blue emitting materials (20 nm)/4,7-Diphenyl-1,10-phenanthroline (Bphen, 30 nm)/lithium quinolate (Liq, 2 nm)/Al (100 nm). In particular, a device using 11,11-dimethyl-3-(10-phenylanthracen-9-yl)-11-Indeno[1,2-]quinoline in emitting layer showed luminous efficiency, power efficiency, and external quantum efficiency of 2.18 cd/A, 1.10 lm/W, 2.20% at 20 mA/cm², respectively, with Commission Internationale d'Énclairage (CIE) coordinates of (0.15, 0.11) at 8.0 V.

摘要

在本研究中，我们通过铃木偶联反应设计并合成了两种使用苯基蒽取代茚并喹啉衍生物的蓝色荧光材料，用于有机发光二极管（OLED）。为了研究它们的电致发光特性，我们使用这两种材料作为发光层（EML）制造了OLED器件，器件结构如下：氧化铟锡（ITO，180 nm）/4,4',4″-三[2-萘基（苯基）-氨基]三苯胺（2-TNATA，30 nm）/N,N'-二苯基-N,N'-（2-萘基）-（1,1'-联苯）-4,4'-二胺（NPB，20 nm）/蓝色发光材料（20 nm）/4,7-二苯基-1,10-菲咯啉（Bphen，30 nm）/喹啉酸锂（Liq，2 nm）/铝（100 nm）。特别地，一种在发光层中使用11,11-二甲基-3-（10-苯基蒽-9-基）-11-茚并[1,2-b]喹啉的器件，在20 mA/cm²时的发光效率、功率效率和外量子效率分别为2.18 cd/A、1.10 lm/W、2.20%，在8.0 V时的国际照明委员会（CIE）坐标为（0.15, 0.11）。
