Organic Field?Effect Transistors Based on Ternary Blends Including a Fluorinated Polymer for Achieving Enhanced Device Stability

The stability of organic semiconductors (OSCs) is strongly hampered by the presence water molecules. One approach that has been proved to lead field-effect transistors with an enhanced performance use blends OSCs insulating binding polymers. In this work, fabrication OSC thin films based on polymeric ternary including a hydrophobic fluorinated polymer reported as novel route engineer long-term reliable (OFET) devices. particular, OFETs bis(triisopropylsilylethynyl)pentacene (TIPS) polystyrene (PS) and poly(pentafluorostyrene) (PFS) are explored. PS:PFS ratio tuned in order find optimum formulation. It shown 20% PFS blend exhibit improved device performance, which reflected low bias stress exceptional environmental stability, without significantly hampering OFET mobility. This work advocates adding small percentage polymers promising realize more stable devices importantly compromising
