Oligothiophenes fused ring materials

Research on organic/polymeric FETs has not been confined to oligothiophene/ poly thiophene materials. Important advances have been made with other classes of materials such as fullerenes [12, 13], fused ring compounds such as pentacene [14, 15], and the phthalocyanines. While most of this chapter is focused on oligo-and poly-thiophene FETs, there are a few brief discussions of FETs with other organic materials to illustrate some key points.
