frontier molecular orbital energy levels, and interchain stacking property of the resulting polymers. These polymers are stable up to 220 °C and decompose to dinitrile compounds with the breaking of Tz linkage at a higher temperature. Efficient bulkheterojunctionsolarcells were fabricated by blending these polymers with (6,6)-phenyl-C71-butyric acid methyl ester (PC71BM), and they reached a power conversion
作为新兴的缺乏电子的新组成部分,s-四嗪(Tz)具有很高的电子亲和力,甚至比常用的苯并噻二唑单元还要高。这种特性使Tz成为低带隙共轭聚合物,特别是有机太阳能电池材料非常有希望的吸电子单元。我们报告的合成和性质的五个交替共聚物的s-四嗪和环戊[2,1-b:3,4-b']二噻吩(CPDT),这是一个噻吩单元桥接。将甲基,己基和/或2-乙基己基引入到噻吩和CPDT单元上,以调节所得聚合物的溶解度,紫外线吸收,前沿分子轨道能级和链间堆积特性。这些聚合物可在高达220°C的温度下保持稳定,并在较高的温度下分解为Tz键,从而分解为二腈化合物。71-丁酸甲基酯(PC 71 BM),在模拟的1.5 m AM / 100 GW / cm 2的AM辐照下,它们的功率转换效率高达5.53%。然后通过原子力显微镜(AFM)分析来自不同聚合物或在不同加工条件下的活性层的形态结构,并将其与器件性能相关联。
