In this study, we designed and synthesized blue emitting materials based on 1, 10-phenanthroline derivatives. 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)/Tris(4-carbazoyl-9-ylphenyl)amine (TCTA) (10 nm)/Blue materials (20 nm)/2,2',2″-(1,3, 5-Benzinetriyl)-tris(1-phenyl-1--benzimidazole) (TPBi) (30 nm)/lithium quinolate (Liq) (2 nm)/Al (100 nm). Particularly, a device using 2-(4-(9,9-dimethylacridin-10(9H)-yl)phenyl)-1-phenyl-1Himidazo[ 4,5-f][1,10] phenanthroline as a blue emitter showed the maximum values of luminous efficiency, power efficiency, and external quantum efficiency of 1.45 cd/A, 1.52 lm/W, 0.99%, respectively with the Commission Internationale d'Énclairage (CIE) () coordinates of (0.16, 0.14) at 8.0 V.
在本研究中，我们基于1,10 - 菲咯啉衍生物设计并合成了蓝色发光材料。使用这些材料的有机发光二极管（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'-二（2-萘基）-（1,1'-联苯）-4,4'-二胺（NPB）（50纳米）/三（4-咔唑-9-基苯基）胺（TCTA）（10纳米）/蓝色材料（20纳米）/2,2',2''-（1,3,5-苯三嗪）-三（1-苯基-1H-苯并咪唑）（TPBi）（30纳米）/喹啉酸锂（Liq）（2纳米）/铝（Al）（100纳米）。特别地，使用2-（4-（9,9-二甲基吖啶-10（9H）-基）苯基）-1-苯基-1H-咪唑并[4,5-f][1,10]菲咯啉作为蓝色发射体的器件在8.0伏时，发光效率、功率效率和外量子效率的最大值分别为1.45坎德拉/安培、1.52流明/瓦、0.99%，国际照明委员会（CIE）色坐标为（0.16, 0.14）。
