Upon applying these materials in bulk heterojunction polymer solar cells, an efficiency of 4.4% is obtained for the best-performing device, with a particularly higher short-circuit current and improved fill factor compared to the pristine alkyl-substituted polymer. Importantly, a non-halogenated solvent – beneficial toward ‘green’

  在有机电子施加的共轭聚合物（特别是光伏和光电检测器）通常表现出相对低的介电常数（ε - [R到光生激子的显著重组损失3-4），其引线。直接的结果是，所产生的设备的性能固有地受到限制。一些努力已指向增加ε - [R光活性有机化合物，但在特定的结构变化对介电常数的影响，并最终装置输出保持的一般知识相当有限。在这项研究中，解决了这个问题。基于4 H-环戊[2,1- b：3,4-合成了一系列的推挽式交替共聚物b ']二噻吩（CPDT）和4 H-噻吩并[3,4- c ]吡咯-4,6（5 H）-二酮（TPD）亚基，目的是通过低聚乙二醇侧提高介电常数链。逐渐增加聚合物主链上乙二醇取代基的数量，以系统地研究其对介电性能的影响。阻抗测量揭示介电常数（高达加倍到ε - [R6.3）相对于参考聚合物。将这些材料应用于本体异质结聚合物太阳能电池后，与原始烷基取代的聚合物相比，性能最佳的器件的效率为4.4％，具有特

  A two-step synthetic protocol involving (i) a Wittig-type carbonyl olefination, and (ii) regioselective alkylation of the exocyclic double bond with LiAlH4 and an alkyl bromide, was developed as an alternative to the recently reported three-step synthetic approach toward asymmetrically substituted/functionalized 4H-cyclopenta[2,1-b:3,4-b]dithiophenes. The two routes are rather complementary, with specific advantages depending on the desired substitution pattern, and are of particular appeal for the construction of semiconducting materials to be applied in organic photovoltaics.
