In this study, we designed and synthesized three blue emitting materials containing dibenzo[b,d]furan and dibenzo[b,d]thiophene. To investigate the electroluminescence (EL) properties, we fabricated devices with following sequences: indium–tin-oxide (180 nm)/N,N'-diphenyl-N,N'-(1-napthyl)-(1,1'-phenyl)-4,4'-diamine (50 nm)/blue emitters (30 nm)/bathophenanthroline (30 nm)/lithium quinolate (2 nm)/Al (100 nm). A device using 1,4-bis(dibenzo[b,d]furan-4-yl)naphthalene showed the deep-blue emission with 1.34% of external quantum efficiency at 30 mA/cm2. The Commission Internationale de l'Eclairage (CIE) coordinates of this device was at 6.0 V.

用于有机发光二极管的含有二苯并[b,d]呋喃和二苯并[b,d]噻吩的蓝色发光材料

在这项研究中，我们设计并合成了三种含有二苯并[b,d]呋喃和二苯并[b,d]噻吩的蓝色发光材料。为了研究电致发光 (EL) 特性，我们制造了具有以下序列的器件：氧化铟锡 (180 nm)/N,N'-二苯基-N,N'-(1-萘基)-(1,1'-苯基)-4,4'-二胺 (50 nm)/蓝色发射体 (30 nm)/bathophenanthroline (30 nm)/喹啉锂 (2 nm)/Al (100 nm)。使用 1,4-双(二苯并[b,d]呋喃-4-基)萘的器件在 30 mA/cm2 下显示出深蓝色发射，外部量子效率为 1.34%。该设备的国际照明委员会 (CIE) 坐标为 6.0 V。
