We have studied the effect of self-assembled monolayer (SAM) on the performance and bias-induced changes in bottom contact, inkjet printed organic thin-film transistors (OTFTs) with 6,13-bis(triisopropylsilylethynyl) pentacene (TIPS pentacene). The device was fabricated using the photo-definable photoacryl (PA) and silver (Ag) as gate insulator and source/drain metal electrodes, respectively. The SAM was formed by immersing the patterned Ag electrodes in pentafluorothiophenol (PFBT) solution or by spin coating of phenethyltrichlorosilane (PTS) on the substrate, and TIPS pentacene was inkjet printed at 90 °C. The OTFT with SAMs exhibited the field-effect mobility of 0.18 cm2/Vs and showed the stretched exponential decay with time constant of 1.13 × 107 s and exponential exponent of 0.28.
