Abstract

An electron-deficient building block BDOPV is developed to construct a new donor-acceptor conjugated polymer BDOPV-2T for high-performance n-type and oxygen-doped ambipolar polymer field-effect transistors. A high electron mobility up to 1.74 cm(2) V(-1) s(-1) is demonstrated under ambient conditions. Furthermore, the oxygen-doping effect and possible mechanism are discussed.
