A series of new highly soluble bispyrrolothiophenes were synthesized from vinyl azides by using transition-metal-catalyzed C-H-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. Our investigations identified that the optical properties and oxidation potential of our compounds were dominated by the pyrrolothiophene unit with a λmax value of approximately 400 nm and oxidation at approximately 1 V. FET devices constructed with thin films of these bispyrrolothiophenes were also fabricated by means of thin-film solution processing. One of these compounds, a bispyrrolothiophene linked with benzothiodiazole, exhibits a mobility of approximately 0.3 cm 2V-1s-1 and the Ion/Ioff value is greater than 106. Highly soluble bispyrrolothiophenes have been synthesized from vinyl azides by using transition-metal-catalyzed C-H bond functionalization (see scheme; TFT=thin-film transistor). The solution-state properties and field-effect-transistor (FET) electrical behavior of these compounds were investigated.
