Medicinal Science Division, Korea Research Institute of Chemical Technology, 100 Jang-Dong, Yusung-Gu, Daejeon 305-600, KoreaReceived September 16, 2003Key Words : Soluble pentacene precursor, Organic thin film transistor, Diels-Alder reaction, Organic semi-conductorOver the past two decades, organic thin-film transistors(OTFTs) based on organic semiconductors have beenenvisioned as a viable alternative to more traditional TFTsbased on inorganic material, such as Si and Ge, which havecharge carrier mobilities about three orders of magnitudehigher. The OTFTs have been used for switching devices oflow-cost electronic application such as integrated circuits,
