To develop the efficient emitters for organic light-emitting diode (OLED), three indeno-type polyaromatic hydrocarbons materials were designed and synthesized through Buchwald-Hartwig amination. OLED devices using these materials were fabricated in the following sequence: indium-tin-oxide (ITO) (180 nm)/'-diphenyl-'-(2-napthyl)-(1,1'-phenyl)-4,4'-diamine (NPB) (50 nm)/Emitting materials () (30 nm)/4,7-diphenyl-1,10-phenanthroline (BPhen) (30 nm)/lithium quinolate (Liq) (2 nm)/Al (100 nm). All devices showed the efficient emissions. In particular, a device using 8,8-dimethyl--diphenyl-8-indeno[2,1-]fluoranthen-6-amine () as efficient emitter showed luminous efficiency, power efficiency, and external quantum efficiency of 8.35 cd/A, 5.70 lm/W, 2.37% at 20 mA/cm², respectively, with Commission Internationale d'Énclairage (CIE) coordinates of (0.37, 0.59) at 6.0 V.
为了开发用于有机发光二极管（OLED）的高效发光体，通过布赫瓦尔德-哈特维希胺化反应设计并合成了三种茚并型多环芳烃材料。使用这些材料的OLED器件按以下顺序制备：氧化铟锡（ITO）（180纳米）/N，N'-二苯基-N，N'-（2-萘基）-（1，1'-联苯）-4，4'-二胺（NPB）（50纳米）/发光材料（）（30纳米）/4，7-二苯基-1，10-菲咯啉（BPhen）（30纳米）/喹啉酸锂（Liq）（2纳米）/铝（Al）（100纳米）。所有器件均显示出高效发光。特别是，使用8，8-二甲基-N，N'-二苯基-8-茚并[2，1-a]荧蒽-6-胺（）作为高效发光体的器件在20毫安/平方厘米时的发光效率、功率效率和外量子效率分别为8.35坎德拉/安培、5.70流明/瓦、2.37%，在6.0伏时的国际照明委员会（CIE）坐标为（0.37，0.59）。
