Abstract

Three novel materials (, and ), based on the indolo[3,2,1-]carbazole and 9-carbazole building blocks, with high triplet energies ( > 2.80 eV) and good thermal stability ( > 101 °C) were synthesized, characterized and applied as host materials in PhOLED devices. In course of the preparation of the materials, an improved protocol for the synthesis of the indolo[3,2,1-]carbazole moiety has been developed. The careful molecular design of the title compounds allowed to avoid excimer formation of the indolo[3,2,1-]carbazole subunits in thin films. Therefore, the improved molecular design broadened the applicability of indolo[3,2,1-]carbazole host materials and significantly enhanced the efficiency of PhOLED devices based on these derivatives compared to previously reported indolo[3,2,1-]carbazole based compounds. Accordingly, employing the newly developed materials red (CE: 32.7 cd A, PE: 31.0 lm W, EQE: 20.4%), green (CE: 81.0 cd A, PE: 87.4 lm W, EQE: 21.5%) and blue (CE: 35.5 cd A, PE: 39.9 lm W, EQE: 18.0%) PhOLED devices with a remarkably low efficiency roll-off at 1000 cd m ( - red: 5%; green: 0%; blue: 6%) were fabricated.

摘要

合成了三种基于吲哚并[3,2,1 -]咔唑和9 -咔唑结构单元的新型材料（、和），它们具有高三线态能量（> 2.80 eV）和良好的热稳定性（> 101 °C），并对其进行了表征，用作磷光有机发光二极管（PhOLED）器件的主体材料。在材料制备过程中，开发了一种改进的合成吲哚并[3,2,1 -]咔唑部分的方案。对标题化合物进行精心的分子设计，避免了薄膜中吲哚并[3,2,1 -]咔唑亚基的激基缔合物形成。因此，改进的分子设计拓宽了吲哚并[3,2,1 -]咔唑主体材料的适用性，与先前报道的基于吲哚并[3,2,1 -]咔唑的化合物相比，显著提高了基于这些衍生物的PhOLED器件的效率。相应地，采用新开发的材料制备了红色（CE：32.7 cd A，PE：31.0 lm W，EQE：20.4%）、绿色（CE：81.0 cd A，PE：87.4 lm W，EQE：21.5%）和蓝色（CE：35.5 cd A，PE：39.9 lm W，EQE：18.0%）的PhOLED器件，在1000 cd m时效率滚降极低（红色：5%；绿色：0%；蓝色：6%）。
