在这里我们报告了通过2,5-二溴-3-烷基硒烯和(E)-1,2-双(三丁基锡烷基)乙烯的聚合反应合成新型聚(3-烷基-2,5-亚硒基亚乙烯基)(PSV)在微波辅助的Stille耦合条件下。制备了含有己基和癸基侧链的聚合物。癸基取代的聚合物在常见的有机溶剂中显示出良好的溶解性,1 H NMR分析表明侧链区域规则性超过90%。该聚合物在溶液中在621 nm处显示最大吸收,成膜时吸收有明显的红移。由PSV制成的薄膜晶体管表现出的空穴载流子迁移率高达0.01 cm 2/(V s)。当将不含羟基的有机电介质用作栅极绝缘体时,聚合物显示出平衡的双极性性能。

A practical and convenient Co-catalyzed alkylation method for the facile introduction of various alkyl chains into organic electronically significant heteroaryl compounds, including thiophenes, furans, selenophenes, and pyrroles, is reported. Under well-optimized reaction conditions, a wide range of alkylated heteroaryl compounds have beeen efficiently prepared in moderate to good isolated yields.
