bandgap of electrochromic polymers is one of the important research topics in electrochromism. To understand clearly the effect of donor unit in donor–acceptor–donor‐type polymers, 2,3‐bis(4‐tert‐butylphenyl)‐5,8‐di(thiophen‐2‐yl)quinoxaline and 2,3‐bis(4‐tert‐butylphenyl)‐5‐(2,3‐dihydrothieno[3,4‐b][1,4]dioxin‐ 5‐yl)‐8‐(thiophen‐2‐yl)quinoxaline were synthesized and polymerized potentiodynamically. Their
调节电致变色聚合物的带隙是电致变色的重要研究主题之一。为了清楚地了解供体单元在供体-受体-供体型聚合物中的作用,即2,3-双(4-叔丁基苯基)-5,8-二(噻吩-2-基)喹喔啉和2,3-双合成(4-叔丁基苯基)-5-(2,3-二氢噻吩并[3,4- b ] [1,4]二恶英-5-基)-8-(噻吩-2-基)喹喔啉并进行电位动力学聚合。他们进行了电化学和光谱电化学研究,并将结果与聚(2,3-双(4-叔丁基苯基)-5,8-双(2,3-二氢噻吩并[3,4- b]] [1,4]二恶英-5-基)喹喔啉)(Gunbas等人,Adv Mater 2008,20,691–695)。聚合物π–π *跃迁的蓝移表明,具有相同受体单元的此类聚合物的带隙与施主单元的电子密度有关。©2011 Wiley Periodicals,Inc.
