A method of regioselectively preparing a pyridine-containing compound is provided. In particular embodiments, the method includes reacting halogen-functionalized pyridal[2,1,3]thiadiazole with organotin-functionalized cyclopenta[2,1-b:3,4-b′]dithiophene or organotin-functionalized indaceno[1,2-b:5,6-b′]dithiophene. Also provided is a method of preparing a polymer. The method includes regioselectively preparing a monomer that includes a pyridal[2,1,3]thiadiazole unit; and reacting the monomer to produce a polymer that includes a regioregular conjugated backbone section, wherein the section includes a repeat unit containing the pyridal[2,1,3]thiadiazole unit. A polymer that includes a regioregular conjugated backbone section, and electronic devices that include the polymer, are also provided.
提供了一种区域选择性制备含吡啶化合物的方法。在特定实施例中,该方法包括将卤素功能化的吡啶[2,1,3]噻二唑与有机锡功能化的环戊[2,1-b:3,4-b']二硫噻吩或有机锡功能化的吲哚并[1,2-b:5,6-b']二硫噻吩反应。还提供了一种制备聚合物的方法。该方法包括区域选择性制备包含吡啶[2,1,3]噻二唑单元的单体,并将单体反应以产生包含区域富集的共轭骨架部分的聚合物,其中该部分包含重复单元,其中包含吡啶[2,1,3]噻二唑单元。还提供了包含区域富集的共轭骨架部分的聚合物和包含该聚合物的电子器件。
