含三苯胺基芳香酰胺的合成及其电致变色、光电性能研究（英文）

Novel aromatic amide containing triphenylamine units: synthesis,electrochromic and photovoltaic properties

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 new series of aromatic amides （AAs） containing thiophenes and triphenylamine （TPA） de- rivatives were reported. All compounds were characterized by 1 H-NMR, FT-IR spectroscopy and Elemen- tal Analysis. The electrochromic, photoelectrical and electrochemical properties of AAs were investigated by UV-vis spectroscopy and cyclic voltammetry （CV） techniques. The obtained results showed that all the anodic coloring films revealed good electrochemical properties and electroehromic stability. At the same time, the coloration changed from the yellow neutral state to the green or purple oxidized state. The AAs not only showed good electrochemical properties and electroehromic stability but also made the pho- tocurrent and photovoltage significantly response upon exposure to on/off light.
