Here we report the synthesis of novel poly(3-alkyl-2,5-selenylenevinylene)s (PSV) by the polymerization of 2,5-dibromo-3-alkylselenophene and (E)-1,2-bis(tributylstannyl)ethylene under microwave-assisted Stille coupling conditions. Polymers containing hexyl and decyl side chains were prepared. The decyl-substituted polymer exhibited good solubility in common organic solvents, and 1H NMR analysis indicated
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。
