摘要

发光电化学池在柔性显示和大面积发光面板的低成本制造方面具有显著优势

但是白光发光电化学池器件的制备一直是一个难题。本文报道了基于阳离子铱离子配合物的柔性黄光发光电化学池

其在6 V时的电流效率高达11.6 cd/A。并将此铱离子配合物与蓝光聚芴材料以一定比例混合

基于此材料制备了白光发光电化学池

其色坐标为(0.31

0.33)

接近标准白光。

Abstract

Light-emitting electrochemical cells (LECs) have a crucial benefit in low cost fabrication processes in flexible and large area illumination panels

but the white light emission remains to be a problem. The fabrication of flexible yellow LECs based on a cationic iridium complex was reported in this paper

which showed yellow electroluminescence with high current efficiency of 11.6 cd/A at 6 V. White light-emitting electrochemical cells were fabricated by blending material mixing polyfluorene with cationic iridium complexes. The cells show white electroluminescence with CIE coordinates of (0.31

0.33)

which is close to standard white emission.
