    摘要: The present invention provides a semiconductor device, especially an organic field effect transistor, comprising a layer comprising a polymer comprising repeating units having a diketopyrrolopyrrole skeleton (DPP polymer) and an acceptor compound having an electron affinity in vacuum of 4.6 eV, or more. The doping of the DPP polymer with the acceptor compound leads to an organic field effect transistor with improved hole mobility, current on/off ratio and controllable threshold shift.
