End substitution of sexithiophene with hexyl groups, α,ω- dihexylsexithiophene (DH-6T), leads to a highly soluble conjugated oligomer. In this paper, we report on the synthesis of an air-stable p-type organic semiconductor, DH-6T. We also report on our analysis of its thermal, optical, and electrical properties. We obtained a stable characteristic curve. The field-effect performance had a mobility of 3.29 × 10-4 cm 2/V s, while the threshold voltage was about -19 V. The current on/off ratio was greater than 106 when the gate voltage was scanned from -40 to 0 V.
