Benzodithiophene Rings as Semiconductor Building Blocks


  • The authors thank R. Opila and H. Krautter for surface analyses and Z. Bao, E. Reichmanis, and R. F. Slusher for useful discussions.


An organic p-type semiconductor based on benzodithiophene building blocks is reported for the first time. The synthesis and electrical and morphological characterization of a dimer compound (see Figure) are described, including field-effect measurements on thin film transistors, X-ray diffraction, molecular modeling, and electron microscopy. The exceptional thermal stability is noted.
