The syntheses of four triptycene-bis(aroyleneimidazole)s-the missing links with respect to the previously reported triptycene-mono(aroyleneimidazole)s and triptycene-tris(aroyleneimidazole)s-are presented. Their optoelectronic properties and use as non-fullerene acceptors in organic photovoltaics with poly({4,8-bis[(2-ethylhexyl)oxy]benzo[1,2-b:4,5-b']dithiophene-2,6-diyl}[3-fluoro-2-(2-ethylhexyl)carbonyl]thieno[3,4-b]thiophenediyl) (PTB7) as a donor are described; these systems reach a maximum power conversion efficiency of 2 %. Furthermore, the effect of molecular symmetry on the photovoltaic device performance is discussed.

作为非富勒烯受体的三蝶烯-双(芳撑咪唑):缺失的环节。

提出了四个三萜-双(芳撑咪唑)的合成-相对于先前报道的三萜-单(芳撑咪唑)和三茂-三(芳撑咪唑)的缺失链接。它们的光电特性以及在聚({4,8-双[(2-乙基己基)氧基]苯并[1,2-b:4,5-b']二噻吩-2,6中的有机光伏中用作非富勒烯受体的用途描述了作为供体的-二基} [3-氟-2-(2-乙基己基)羰基]噻吩并[3,4-b]噻吩二基)(PTB7);这些系统的最大功率转换效率达到2%。此外,讨论了分子对称性对光伏器件性能的影响。
