backbone as the acceptor unit and thiophene derivatives as the donor unit were prepared by Stille coupling. Thiophene, 3-hexyl thiophene and 3,4-ethylenedioxythiophene were used as the donor units to understand the effects of donor unit on electrochemical and optoelectronic properties of the resulting polymers. Electroactivity of monomers and redox behavior of their polymers were investigated by cyclic
制备了一系列主链上含有10,11,12,13-四氢二苯并[ a,c ]吩嗪部分作为受体单元和噻吩衍生物作为供体单元的供体-受体-供体(DAD)π型共轭单体。斯蒂尔耦合。噻吩,3-己基噻吩和3,4-乙撑二氧噻吩用作供体单元,以了解供体单元对所得聚合物的电化学和光电性能的影响。通过循环伏安法研究了单体的电活性及其聚合物的氧化还原行为。芳族结构上强供电子乙二氧基的存在增加了2,7-双(2,3-二氢噻吩并[3,4- b ] [1,4]二恶英-5-基)-10上的电子密度, 11,12,13-四氢二苯并[a,c ]吩嗪(DTBP),因此DTBP的氧化电势比2,7-双(4-己基噻吩-2-基)-10,11,12,13-四氢二苯并[ a,c c ]吩嗪(HTBP)和2,7-二(噻吩-2-基)-10,11,12,13-四氢二苯并[ a,c ]吩嗪(TTBP)。电子带隙,其定义为π-π的发作*跃迁,被发现是2.5电子伏特为HTBP,为2
