In this study, we present a 5,8-bis(3,4-ethylenedioxythiophene)quinoxaline monomer with two 4-(octyloxy)phenyl side chains (EDOTPQ) that can be electropolymerized on ITO glass in standard electrolytes containing lithium salts and propylene carbonate as solvent. The electrochemically deposited PEDOTPQ layers show very good adhesion and homogeneity on ITO. The green-colored polymer thin films exhibit promising electrochromic (EC) properties and are interesting for applications such as adaptive camouflage, as well as smart displays, labels, and sensors. Novel organic-inorganic (hybrid) EC cell configurations were realized with Prussian blue (PB) or titanium-vanadium oxide (TiVO) as ion storage electrodes, showing a highly reversible and fast color change from green to light yellow.
在本研究中,我们展示了一种带有两个4-(辛氧基)苯基侧链的5,8-双(3,4-亚乙基二氧噻吩)喹喔啉单体(EDOTPQ),它可以在含有锂盐和碳酸丙烯酯作为溶剂的标准电解质中在ITO玻璃上进行电聚合。电化学沉积的PEDOTPQ层在ITO上表现出非常好的附着力和均匀性。绿色聚合物薄膜展现出有前景的电致变色(EC)特性,并且对于诸如自适应伪装以及智能显示器、标签和传感器等应用而言很有吸引力。用普鲁士蓝(PB)或钛钒氧化物(TiVO)作为离子存储电极实现了新型有机-无机(混合)EC电池配置,显示出从绿色到浅黄色的高度可逆且快速的颜色变化。
