Abstract

A series of blue fluorescent materials 1-6 based on N, N-diphenyl aminofluorene styryl derivatives with six heteroatoms (PhOPh, PhSPh, PhSePh, PhPPh2, thiophene and dibenzothiophene), were synthesized and multilayer devices were fabricated. Interestingly, the EL efficiencies were very sensitive to the structural features of dopants in the emitting layers. Particularly, by using 1 as a dopant in emitting layer, a high-efficiency blue OLED was fabricated, showing the maximum luminance of 10420 cd/m2 at 11 V, the luminous efficiency of 8.6 cd/A at 20 mA/cm2, the power efficiency of 3.4 Im/W at 20 mA/cm2 and had a blue color with the CIE coordinates of (0.147, 0.156) at 8.0 V.

摘要

合成了一系列基于含六个杂原子（苯氧基苯、苯硫基苯、苯硒基苯、二苯基膦、噻吩和二苯并噻吩）的N，N - 二苯基氨基芴苯乙烯基衍生物的蓝色荧光材料1 - 6，并制备了多层器件。有趣的是，电致发光效率对发光层中掺杂剂的结构特征非常敏感。特别地，通过在发光层中使用1作为掺杂剂，制备了一种高效蓝色有机发光二极管，在11V时最大亮度为10420 cd/m²，在20 mA/cm²时发光效率为8.6 cd/A，在20 mA/cm²时功率效率为3.4 Im/W，并且在8.0V时具有CIE坐标为(0.147, 0.156)的蓝色。
