N2 - We report the high performance, 6,13-bis(triisopropyl silylethynyl) pentacene (TIPS-pentacene) organic thin-film transistors (OTFTs) by ink-jet printing on a thin polymer layer. The OTFT with polymer/TIPS-pentacene exhibited the saturation field-effect mobility (μ sat) of 1.11 cm 2/Vs and threshold voltage (V th) of -0.41 V. In contrast, the ink-jet printed TIPS-pentacene TFT without PS layer shows the μ sat of 0.36 cm 2/Vs and V th of -0.62 V. The improved performance of polymer blended OTFT appears to be due to the improved crystallinity of the polymer blended TIPS-pentacene layer.
