Organic field-effect transistors (OFETs) are advancing rapidly in terms of their applications in low-cost large-area thin film transistors. However, PFETs with high carrier mobility and long-time stability are usually achieved in low-humidity and inert atmosphere. Therefore, to design new
polymers for high-mobility PFETs with ambient-stability is still of great challenge. On the other
hand, the structure-property relationship is important for designing new organic materials for
optoelectronics. Although several design strategies and even computational methods have been proposed for small molecular OFETs, rational design strategy for PFETs is seldom reported.
