以噻吩和不同的三苯胺衍生物为原料通过酰胺化反应制备了一系列芳香酰胺,并对它们进行了核磁、红外和元素分析表征,同时利用紫外光谱和循环伏安法进行了电致变色、电化学及光电性能的研究。结果表明,在电致变色过程中,所有的阳极变色薄膜展现出良好的电化学性能和电致变色稳定性,并伴随着不同的颜色变化,即由黄色变为绿色或者由黄色变为绿色最后到紫色。同时得到芳香酰胺不仅具有好的电化学和电致变色稳定性而且能够对光产生显著的电压和电流变化特性。
A series of aromatic amides were prepared by amidation reaction using thiophene and different triphenylamine derivatives as raw materials. Their structures were characterized by NMR, IR and elemental analysis. Their electrochromic properties were characterized by UV-Vis and cyclic voltammetry. Electrochemical and Optoelectronic Properties. The results show that all electrochromic films exhibit good electrochemical performance and electrochromic stability during electrochromic process with different color changes from yellow to green or yellow to green finally To purple. At the same time, aromatic amides not only have good electrochemical and electrochromic stability but also produce significant voltage and current change characteristics to light.
