초록

In this paper, we investigated the electrical properties change of 6,13-bis(triisopropyl-silylethynyl) pentacene (TIPS-pentacene) depending on polymer blend. We fabricated organic thin film transistor (OTFT) using blending solution of small molecule and polymer. In this study poly(2-methoxy-5-(2-ethyl-hexyloxy)-1,4-phenylene-vinylene) (MEH-PPV), poly (9-vinylcarbazole) (PVK), poly [N,N'-bis(4-butylphenyl)-N,N'-bis(phenyl)benzidine] (poly-TPD), poly(${\alpha}$-methyl styrene), Poly(methyl methacrylate) (PMMA) are used as a polymer. Fabricated OTFT with blending solution of TIPS-pentacene and PVK shows best performance in this experiment. OTFT fabricated by blending solution of TIPS-pentacene and PVK shows field effect mobility of 0.0189 $cm^2/V{\cdot}s$, on/off ratio of 1.9E-5 and threshold voltage of 7.4 V.
