Abstract

Using the small molecule organic semiconductor 6,13-bis(triisopropyl- silylethynyl) pentacene (TIPS-pentacene), the authors have fabricated the solution-processed organic thin film transistors (OTFTs) with carrier mobility >1 cm2 V s, current on/off ratio greater than 107, and subthreshold slope <0.3 V /decade. The high mobility TIPS-pentacene solution-processed films are deposited from high boiling point solvents and show strong molecular ordering including molecular terracing. Film ordering varies substantially for different solvents and film deposition techniques and OTFT mobility correlates well with film ordering.
