基于含芴菲并咪唑衍生物的可湿法加工的蓝光有机电致发光器件
Solution-processable Blue Organic Light-emitting Diodes Based on Fluorene of Phenanthroimidazole Derivatives
摘要
设计合成了一种新型A-D-A含芴菲并咪唑和炔基基团的蓝光分子(FI), 采用紫外吸收、光致发光光谱和循环伏安对材料进行了表征, 发现该物质具有稳定的蓝光发射。采用旋涂的方法制备了非掺杂蓝光有机发光二极管, 器件的最大电流效率为1.52 cd·A-1,最大功率效率为0.63 lm·W-1.
Abstract
A novel A-D-A blue emitter containing fluorene, phenanthroimidazole and acetylene group moieties was synthesized and characterized, named as FI. Its photophysical and photochemical properties were systematically investigated. The results showed FI exhibits excellent solubility, fluorescence, thermal stability and film formation, which is a good candidate for the fabrication of solution-processable organic light-emitting diodes. A non-doped blue organic light-emitting diode based on FI as the emitter showed the maximum luminance efficiency of 1.52 cd·A-1, and the maximum power efficiency could reach 0.63 lm·W-1.
