a b s t r a c t The authors fabricated thin films by solution processes using liquid-crystalline (LC) semi-conductors, 5-alkyl-5’’-(4-hexyltetrafluorophenyl)-2,2’:5’,2’’-terthiophene (2–5). Films of applicability and low cost production. However, the mobil-ity of OFETs prepared by such a process is usually lower than that of devices fabricated by vacuum deposition. In addition, soluble conjugated polymers [1–3], solution-Recently, liquid-crystalline (LC) semiconductors have emerged as promising materials for organic electronics [6–8]. They are solution-processable because of the ther-mal movement of the long alkyl chains attached to the LC molecules, which can self-assemble into large-area do-mains with a crystal-like structure and low defect density. Thus, the influence of grain boundaries, which seriously hinder charge carrier transport in polycrystalline materials
