  Methods for preparing benzodithiophenes

  摘要：

  本发明揭示了一种向苯并二噻吩中添加取代基的方法。将苯并二噻吩与试剂反应，直接将取代基添加到苯并二噻吩的苯环核上。该方法省略了之前工艺中的步骤，消除了氢化的需要，从而实现了更安全和更可扩展的工艺。得到的苯并二噻吩适用于半导体聚合物，并没有性能损失。

  Methods of adding substituents to a benzodithiophene are disclosed. A benzodithiophene is reacted with a reagent to directly add the substituent to the benzene core of the benzodithiophene. This method eliminates steps from prior process and eliminates the need for hydrogenation, allowing for a safer and more scaleable process. The resulting benzodithiophenes are suitable for use in semiconductor polymers and have no loss of performance.

  Disclosed is a process for purifying monomers of Formula (II): wherein R 1 and R 2 are independently selected from alkyl, substituted alkyl, aryl, substituted aryl, alkoxy, substituted alkoxy, and halogen; and R′ is selected from hydrogen, alkyl, substituted alkyl, aryl, substituted aryl, alkoxy, substituted alkoxy, and halogen. After the monomer is synthesized, it is purified by column chromatography using neutral alumina and hexane as an eluent. The resulting product can also be further recrystallized using isopropanol, hexane, heptane, or toluene. Polymers formed from the purified monomer exhibit higher mobility and increased reproducibility of the mobility.
