Organic field-effect transistors (OFETs) are of great interest in applications such as display drivers, identification tags, and smart cards because they have the advantages of being inexpensive, flexible, and lightweight. One of critical active components of OTFTs is the semiconductor which essentially dictates the transistor performance. Polymer semiconductors have received special attention for OTFTs by virtue of their solution processablility and good film-forming property-the former renders them compatible with inexpensive common liquid deposition techniques while the latter renders them compatible with plastic substrates to enable flexible electronic design. In this paper, we reported the synthesis and characterization of new alternating fluorene/indolocarbazole copolymer as OTFT
