namely diethyl 2,5-di(thiophen-2-yl)-1H-pyrrole-3,4-dicarboxylate (1), was copolymerized with 3,4-ethylenedioxythiophene (EDOT) via electrochemical method. The copolymer exhibits multicolor electrochromic property: It is found that the copolymer, poly(1-co-EDOT), has a specific optical band gap (1.71 eV) to reflect and/or transmit reddish brown color in the neutral state, and it can be switched to reddish
通过电化学方法,将新化合物2,5-二(噻吩-2-基)-1H-吡咯-3,4-二羧酸二乙酯(1)与3,4-乙撑二氧噻吩(EDOT)共聚。该共聚物具有多色电致变色特性:发现该共聚物(聚(1 -co-EDOT))具有特定的光学带隙(1.71 eV),可以反射和/或透射中性状态的红棕色,并且可以在很短的切换时间(1.0 s)内被氧化后,可切换为红橙色,橙色,黄绿色和蓝色。重要的是,这些颜色对于伪装和/或全色电致变色设备/显示应用至关重要。除这些以外,所得共聚物在500nm下的着色效率为173cm 2 /℃。
