Abstract

Two blue fluorescent materials based on diphenylaminoarylvinyl-substituted diphenylanthracene have been synthesized. Multilayered organic light-emitting diodes (OLED) with the following sequence; ITO/NPB (50 nm)/Blue materials (30 nm)/Bphen (30 nm)/Liq (2 nm)/Al (100 nm) were fabricated using these materials as emitters. Two devices exhibited blue electroluminescence. Particularly, a device using 6-(4-(10-phenylanthracen-9-yl)styryl)-,-diphenylnaphthalen-2-amine (2) exhibited blue emission with a luminance efficiency, a power efficiency, an external quantum efficiency and CIE coordinates of 5.69 cd/A, 1.99 lm/W, 3.39% at 100 mA/cm² and ( = 0.19, =0.31) at 8.0 V, respectively.

摘要

已合成了两种基于二苯胺基芳基乙烯基取代二苯并蒽的蓝色荧光材料。使用这些材料作为发光体，制备了具有以下结构的多层有机发光二极管（OLED）：ITO/NPB（50纳米）/蓝色材料（30纳米）/Bphen（30纳米）/Liq（2纳米）/Al（100纳米）。两个器件均呈现蓝色电致发光。特别地，使用6-(4-(10-苯基蒽-9-基)苯乙烯基)-α,α-二苯基萘-2-胺（2）的器件在100 mA/cm²时的发光效率、功率效率、外量子效率和CIE坐标分别为5.69 cd/A、1.99 lm/W、3.39%，在8.0 V时为（x = 0.19，y = 0.31）。
