摘要/Abstract

摘要： 设计并合成了一种由咔唑和噁二唑基团构成的,具有双极载流子传导特性的新型主体材料C1PBD。通过对C1PBD的光物理和电化学性能进行研究,证明这种新型的双极主体材料可以用作为蓝色荧光器件的主体材料.利用传统蓝色荧光掺杂材料TBPe,制备了C1PBD作为主体材料的器件,并对其性能进行了表征,器件开启电压约为3.2 V,最大电流效率达到2.26 cd/A,器件表现出稳定的蓝色发光,CIE值稳定在(0.14,0.14),展现了C1PBD作为主体材料的良好性能.

关键词: 有机电致发光器件(OLED), 双极主体材料, 蓝色荧光

Abstract: A new bipolar host material C1PBD,constituted by carbazole and oxadiazole groups,has been designed,synthesized and characterized.The optical and electrochemical properties of C1PBD prove this new bipolar host could be used as the blue fluorescence host.The OLED based on C1PBD and TBPe exhibited a low turn-on voltage(3.2 V with a brightness of 1 cd·m^-2),a high efficiency(2.26 cd/A for the max current efficiency),and a stable blue emission with a CIE coordinate of(0.14,0.14).

Key words: OLED, bipolar host material, blue fluorescence
