以联苯为原料合成了6种4,4’-联苯二甲酸酯类化合物,通过核磁、红外对其结构进行了确认,并使用电化学工作站和紫外光谱对其电化学性质作了初步研究。组装了以4,4’-联苯二甲酸酯为电致变色材料的简易EC器件,当施加3.0V电压时器件显示黄绿色,而施加3.6V电压时显示为洋红色,实现了从无色到三原色的转变。而且,4,4’-联苯二甲酸酯合成操作简单,成本低廉,是一类新型的电致变色材料。

Six 4,4’-biphenyl dicarboxylic acid ester were synthesized with biphenyl as raw material and their structure were confirmed by 1H NMR,IR.Their electrochemical properties and spectrachemical properties were examined by electrochemical working station and UV-Vis spectra.It was found that 4,4’-biphenyl dicarboxylic acid ester as electrochromic material in the composite electrochromic device（ECD） showed reversible,clear color changes from yellow-green to red when the voltage from 3.0 to 3.6V.The synthesized 4,4’-biphenyl dicarboxylic acid esters are promising candidate materials for visible ECDs,for their outstanding electrochromic behaviors and the cheap original stuff and short synthetic routes.
