Anthanthrone and its derivatives are large polycyclic aromatic compounds (PACs) that pose a number of challenges for incorporation into the structure of soluble conjugated polymers. For the first time, this group of PACs was employed as the building blocks for the synthesis of copolymers (P1–P5) based on poly[(arylene ethynylene)-alt-(arylene vinylene)]s backbone (−Ph–C≡C–Anth–C≡C–Ph–CH═CH–Ph–CH═CH−)_n. During the synthesis of P1–P5, different alkyloxy side chains were incorporated in order to tune the properties of the polymers. Of the copolymer series only P1 (containing anthanthrone and branched 2-ethylhexyloxy side chains on phenylenes), P2 and P3 (for which the anthanthrones containing carbonyl groups were converted to anthanthrene containing alkyloxy substituents) were soluble. The photophysical, electrochemical, electroluminescent and photovoltaic properties of P1–P3 are reported, compared and discussed with respect to the effects of side chains.

聚[（亚芳基亚乙炔基） - ALT - （亚芳基亚乙烯基）]基于蒽嵌蒽醌及其衍生物S：合成和光物理，电化学，电致发光，和光伏特性

蒽酮及其衍生物是大型多环芳族化合物（PAC），对于将其掺入可溶性共轭聚合物的结构提出了许多挑战。首次，这组PAC的被用作用于共聚物（合成的构建块P1 - P5）基于聚[（亚芳基亚乙炔基） - ALT - （亚芳基亚乙烯基）] S骨架（-Ph-C≡C –Anth–C≡C–Ph–CH═CH–Ph–CH═CH-）_n。在P1 - P5的合成过程中，为了调节聚合物的性能，引入了不同的烷氧基侧链。在共聚物系列中，只有P1（在蒽上含有蒽酮和支链的2-乙基己氧基侧链），P2及P3（其为含羰基的蒽嵌蒽醌转化为蒽嵌蒽含烷氧基取代基）是可溶的。报道了P1 - P3的光物理，电化学，电致发光和光伏特性，并就侧链的影响进行了比较和讨论。
