highly soluble bispyrrolothiophenes were synthesized from vinyl azides by using transition‐metal‐catalyzed CH‐bond functionalization. In addition to modifying the substituents present on the end‐pyrrolothiophene moieties, the arene linker in between the two units was also varied. The solution‐state properties and field‐effect‐transistor (FET) electrical behavior of these bispyrrolothiophenes was compared
一系列新的高度可溶性bispyrrolothiophenes通过使用过渡金属催化的C来自乙烯基基叠氮化物的合成氢键官能化。除了修饰存在于吡咯并噻吩末端的取代基外,两个单元之间的芳烃连接基也发生了变化。比较了这些双吡咯并噻吩的溶液状态性质和场效应晶体管(FET)的电性能。我们的研究表明,我们化合物的光学性质和氧化潜能主要由具有最大λ的吡咯并噻吩单元决定。 大约400 nm的电导率和大约1 V的氧化值。用这些双吡咯并噻吩的薄膜构造的FET器件也通过薄膜溶液处理来制造。这些化合物之一是与苯并硫基二唑连接的双吡咯并噻吩,其迁移率约为0.3 cm 2 V -1 s -1,I on / I off值大于10 6。
