In this paper, we investigated the effect of solvent on electrical properties of triisopropylsilyl (TIPS) pentacene organic thin-film transistors (OTFTs). The TIPS pentacene was spin coated by using anisole, chlorobenzene, p-xylene, chloroform and toluene as solvent. Fabricated OTFT with anisole showed field-effect mobility of 0.02 ㎠/Vㆍs, on/off ratio 1.3×10³ and threshold voltage of 2.8 V. In contrast, with chloroform the mobility was 5.8×10?? ㎠/Vs, on/off ratio 1.1×10² and threshold voltage of 1.7 V.
