Highly regioregular conducting polymers such as poly(3-substituted thiophene)s (rrP3STs) are an important class of π-conjugated polymers that can be used in plastic electronic devices such as solar cells and field-effect transistors. But the current state of the art syntheses of rrP3STs all involve transition-metal-catalyzed cross-coupling of a heteroaryl halide or pseudohalide with a heteroaryl organometallic reagent. In this work, an efficient and mild method was developed using direct cross-coupling of sp² C–H bonds. More importantly, the method not only gave generally high regioregularity (up to 99%) but also can be applied for a series of substrate compounds with various structures and substituted groups. This should provide a general and direct way for the easy access to many functional/conducting polymers.

直接CH耦合法制备具有高区域规则性的π共轭功能聚合物

高度规整的导电聚合物，例如聚（3-取代的噻吩）（rrP3ST），是一类重要的π共轭聚合物，可用于塑料电子设备，例如太阳能电池和场效应晶体管。但是，rrP3ST的最新合成技术都涉及杂芳基卤化物或假卤化物与杂芳基有机金属试剂的过渡金属催化交叉偶联。在这项工作中，开发了一种使用sp ^2的直接交叉耦合的有效而温和的方法碳氢键。更重要的是，该方法不仅通常具有很高的区域规则性（高达99％），而且可以应用于一系列具有各种结构和取代基的底物化合物。这应该提供一种容易获得许多功能/导电聚合物的通用直接方法。
