Difluorobenzimidazole-decorated helical perylene diimide dimers for high-performance n-type organic field-effect transistors

N-type benzimidazole and difluorobenzimidazole fused perylene diimide dimer semiconductors were synthesized and a remarkable electronic mobility of 0.13 cm 2 V −1 s −1 was obtained for a FMBI-PDI2-based organic field-effect transistor (OFET).
