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
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。
