Over the past decade, OTFTs (Organic Thin-Film Transistors) act as a key component of the radio frequency identification (RFID) tags, biological sensors and flexible display have a broad application prospects because of the advantages of low cost, large area and flexible substrate . Material design and device engineering are both important approaches to generate performance enhancement. In this study, we demonstrate high-performance OTFTs with mobility of 0.15cm 2V -1S -1 using a novel semiconductor based on Peri-xanthenoxanthene  derivative, we also aim to reduce threshold voltage through the modification of insulator layer and using different structure of device. The result shows that the modification of insulator layer using a thin film of polymer is one useful strategy for reduce threshold voltage of device.
