A series of new highly soluble bispyrrolothio- phenes were synthesized from vinyl azides by using transi- tion-metal-catalyzed CH-bond functionalization. In addition to modifying the substituents present on the end-pyrrolo- thiophene 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 bispyrrolo- thiophenes was compared. Our investigations identified that the optical properties and oxidation potential of our com- pounds were dominated by the pyrrolothiophene unit with a lmax value of approximately 400 nm and oxidation at ap- proximately 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 2 V 1 s 1 and the Ion/Ioff value is greater than 10 6 . |
