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)。
