Multi-vinyl linked benzothiadiazole conjugated polymers: high performance, low crystalline material for transistors

In this work, we proposed a multi-vinyl linker fusing strategy for designing low crystallinity, high performance materials for organic field effect transistors. A corresponding conjugated polymer, PTBTV, base was synthesized, exhibiting an impressive hole mobility of up to 3.2 cm² V^-1 s^-1, yet grazing incidence X-ray diffraction revealed a relatively weak crystallinity in the thin film.
